2. Q2 · Fractions and Decimals

   A man spent 2/5 of his salary on rent and 1/4 on food. If he has Rs. 7000 left, what was his total salary?

   • A. Rs. 18000
   • B. Rs. 20000
   • C. Rs. 22000
   • D. Rs. 24000
   Answer and solution

   Answer: B

   Total spent = 2/5 + 1/4 = 8/20 + 5/20 = 13/20. Remaining fraction = 1 - 13/20 = 7/20. If 7/20 of salary = Rs. 7000, then total salary = 7000 × 20/7 = Rs. 20000.

3. Q3 · Time and Work

   A and B together can finish a work in 12 days. If A alone can finish it in 20 days, in how many days can B finish the work alone?

   • B. 28 days
   • C. 25 days
   • D. 32 days
   Answer and solution

   Answer: A

   1/A + 1/B = 1/12. So 1/20 + 1/B = 1/12. 1/B = 1/12 – 1/20 = (5-3)/60 = 2/60 = 1/30. B takes 30 days.

4. Q4 · LCM and HCF

   The HCF of two numbers is 12 and their LCM is 360. If one number is 60, what is the other number?

   • A. 84
   • B. 72
   • C. 68
   • D. 78
   Answer and solution
