Your basics get stronger, so school exams start to feel lighter. You learn to work quickly without panicking. And it gives you a head start for classes 9 and 10, where the questions get tougher.

It runs chapter by chapter, and I&#8217;ve added a note wherever students commonly slip.<\/span><\/p><h4><b>Rational Numbers<\/b><\/h4><p><b>Q1. Find a rational number between 1\/3 and 1\/2.<\/b><\/p><p><span style=\"font-weight: 400;\">The quickest way is to take the average. (1\/3 + 1\/2) \u00f7 2 = 5\/12. Since 0.33 &lt; 0.42 &lt; 0.5, the answer is <\/span><b>5\/12<\/b><span style=\"font-weight: 400;\">.<\/span><\/p><p><b>Q2. The sum of two rational numbers is 5\/6. One of them is \u22122\/3. Find the other.<\/b><\/p><p><span style=\"font-weight: 400;\">Subtract the known number from the sum: 5\/6 \u2212 (\u22122\/3) = 5\/6 + 4\/6 = <\/span><b>3\/2<\/b><span style=\"font-weight: 400;\">.<\/span><\/p><h4><b>Linear Equations<\/b><\/h4><p><b>Q3. Solve (x + 2)\/3 \u2212 (x \u2212 1)\/4 = 1.<\/b><\/p><p><span style=\"font-weight: 400;\">Clear the fractions first by multiplying everything by 12:<\/span><\/p><p><span style=\"font-weight: 400;\">4(x + 2) \u2212 3(x \u2212 1) = 12<\/span><span style=\"font-weight: 400;\"><br \/><\/span><span style=\"font-weight: 400;\"> 4x + 8 \u2212 3x + 3 = 12<\/span><span style=\"font-weight: 400;\"><br \/><\/span><span style=\"font-weight: 400;\"> x = <\/span><b>1<\/b><\/p><p><span style=\"font-weight: 400;\">Be careful with the minus sign before the second bracket. It changes both terms inside, and writing \u22123x \u2212 3 is one of the most common slips on this type of question.<\/span><\/p><p><b>Q4. A father is three times as old as his son. After 10 years he will be twice as old. Find their present ages.<\/b><\/p><p><span style=\"font-weight: 400;\">Let the son be x, so the father is 3x. In ten years: 3x + 10 = 2(x + 10), which gives x = 10. The son is <\/span><b>10<\/b><span style=\"font-weight: 400;\"> and the father is <\/span><b>30<\/b><span style=\"font-weight: 400;\">.<\/span><\/p><p><b>Q5. The digits of a two-digit number add up to 9. Reversing the digits gives a number 27 more than the original. Find the number.<\/b><\/p><p><span style=\"font-weight: 400;\">Let the digits be t (tens) and u (units), so t + u = 9. The reversed number minus the original is (10u + t) \u2212 (10t + u) = 9(u \u2212 t), and that equals 27, so u \u2212 t = 3. Now you have two simple equations: u = 6 and t = 3. The number is <\/span><b>36<\/b><span style=\"font-weight: 400;\">, and 63 \u2212 36 = 27 confirms it.<\/span><\/p><h4><b>Quadrilaterals<\/b><\/h4><p><b>Q6. The angles of a quadrilateral are in the ratio 2 : 3 : 4 : 6. Find the largest.<\/b><\/p><p><span style=\"font-weight: 400;\">The angles add up to 360\u00b0 and the ratio has 15 parts, so one part is 24\u00b0. The largest angle is 6 \u00d7 24\u00b0 = <\/span><b>144\u00b0<\/b><span style=\"font-weight: 400;\">.<\/span><\/p><p><b>Q7. Each exterior angle of a regular polygon is 40\u00b0. How many sides does it have, and what is each interior angle?<\/b><\/p><p><span style=\"font-weight: 400;\">Exterior angles always total 360\u00b0, so there are 360 \u00f7 40 = <\/span><b>9 sides<\/b><span style=\"font-weight: 400;\">. Each interior angle is 180\u00b0 \u2212 40\u00b0 = <\/span><b>140\u00b0<\/b><span style=\"font-weight: 400;\">.<\/span><\/p><h4><b>Probability<\/b><\/h4><p><b>Q8. A die is rolled once. What is the probability of getting a prime number?<\/b><\/p><p><span style=\"font-weight: 400;\">The primes on a die are 2, 3 and 5, so that&#8217;s 3 out of 6, or <\/span><b>1\/2<\/b><span style=\"font-weight: 400;\">. Notice that 1 is not prime. Students forget this more than you&#8217;d expect.<\/span><\/p><h4><b>Squares, Cubes and Roots<\/b><\/h4><p><b>Q9. Find the smallest number by which 1620 should be multiplied to get a perfect square.<\/b><\/p><p><span style=\"font-weight: 400;\">Write 1620 = 2\u00b2 \u00d7 3\u2074 \u00d7 5. Every prime appears in a pair except 5, so multiply by <\/span><b>5<\/b><span style=\"font-weight: 400;\">. You get 8100, which is 90\u00b2.<\/span><\/p><p><b>Q10. Find the square root of 7056 using prime factorisation.<\/b><\/p><p><span style=\"font-weight: 400;\">7056 = 2\u2074 \u00d7 3\u00b2 \u00d7 7\u00b2. Take one from each pair: 2\u00b2 \u00d7 3 \u00d7 7 = <\/span><b>84<\/b><span style=\"font-weight: 400;\">.<\/span><\/p><p><b>Q11. How many natural numbers lie between 30\u00b2 and 31\u00b2?<\/b><\/p><p><span style=\"font-weight: 400;\">Between n\u00b2 and (n + 1)\u00b2 there are 2n numbers. Here that&#8217;s <\/span><b>60<\/b><span style=\"font-weight: 400;\">. It&#8217;s worth remembering as a shortcut, because it comes up often.<\/span><\/p><p><b>Q12. By what smallest number should 1372 be divided to make it a perfect cube?<\/b><\/p><p><span style=\"font-weight: 400;\">1372 = 2\u00b2 \u00d7 7\u00b3. The 7\u00b3 is already a cube, but the 2\u00b2 is not, so divide by 2\u00b2 = <\/span><b>4<\/b><span style=\"font-weight: 400;\">. That leaves 343, which is 7\u00b3.<\/span><\/p><h4><b>Comparing Quantities<\/b><\/h4><p><b>Q13. A shopkeeper marks an article 25% above cost and then gives a 10% discount. Find his profit percent.<\/b><\/p><p><span style=\"font-weight: 400;\">Assume the cost price is \u20b9100. The marked price is \u20b9125, and after a 10% discount (\u20b912.50 off) the selling price is \u20b9112.50. Profit = <\/span><b>12.5%<\/b><span style=\"font-weight: 400;\">. The discount applies to the marked price, not the cost price. That&#8217;s the whole trick.<\/span><\/p><p><b>Q14. Find the compound interest on \u20b910,000 for 2 years at 10% per annum, compounded annually.<\/b><\/p><p><span style=\"font-weight: 400;\">Amount = 10,000 \u00d7 1.1 \u00d7 1.1 = \u20b912,100. Interest = 12,100 \u2212 10,000 = <\/span><b>\u20b92,100<\/b><span style=\"font-weight: 400;\">.<\/span><\/p><h4><b>Algebra<\/b><\/h4><p><b>Q15. If a + b = 10 and ab = 21, find a\u00b2 + b\u00b2.<\/b><\/p><p><span style=\"font-weight: 400;\">You don&#8217;t need to find a and b at all. Use a\u00b2 + b\u00b2 = (a + b)\u00b2 \u2212 2ab = 100 \u2212 42 = <\/span><b>58<\/b><span style=\"font-weight: 400;\">.<\/span><\/p><p><b>Q16. Factorise x\u00b2 \u2212 5x \u2212 24.<\/b><\/p><p><span style=\"font-weight: 400;\">Look for two numbers that multiply to \u221224 and add to \u22125: they are \u22128 and 3. So x\u00b2 \u2212 8x + 3x \u2212 24 = x(x \u2212 8) + 3(x \u2212 8) = <\/span><b>(x \u2212 8)(x + 3)<\/b><span style=\"font-weight: 400;\">.<\/span><\/p><h4><b>Exponents<\/b><\/h4><p><b>Q17.

Then take the reciprocal to get <\/span><b>12\/7<\/b><span style=\"font-weight: 400;\">. Flipping each term separately is the usual wrong turn here.<\/span><\/p><h4><b>Proportion<\/b><\/h4><p><b>Q18. 12 workers finish a job in 15 days. How long will 20 workers take?<\/b><\/p><p><span style=\"font-weight: 400;\">More workers means fewer days, so it&#8217;s an inverse proportion. 12 \u00d7 15 = 20 \u00d7 d, which gives <\/span><b>d = 9 days<\/b><span style=\"font-weight: 400;\">.<\/span><\/p><h4><b>Mensuration<\/b><\/h4><p><b>Q19.
