Solutions

S6. Ans.(d)

Sol. (19.97% of 781) + ? + (30% of 87) = 252 

Or (20% of 780) + ? + (30 % of 87) = 252 

Or 156 + ? + 26 ≈ 252 

Or 182 + ? ≈ 252 

Or ? ≈ 252 - 182  

Or ? = 70  

S9. Ans.(c)

Sol. Here, the given expression can also be written as 

8400 ÷ 400 × 15 

Or 21 × 15 = 315 ≈ 335 

S12. Ans.(b)

Sol. Here, the given expression can also be written as 

32 × 2800 ÷ 560 + 120 = ? 

[applying BODMAS] 

Or ? = 32 × 5 + 120 

Or ? = 160 + 120 = 280 ≈ 284 

S13. Ans.(a)

Sol. Here, the given expression can also be written as 

15% of 725 × 13% of 643 = ? 

Or ? 15/100×725×13/100×643 

Or ? = 15 × 7.25 × 13 × 6.43 

Or ? = 15 × 7.25 × 13 × 6.5 

Or ? = 195 × 7.25 × 6.5 

= 9189.375 ≈ 9110 

S14. Ans.(d)

Sol. Here, the given expression can also be written as 

2418 + 88 ÷ 14 × 6 = ? 

Or ? = 2418 + 6.3 × 6 

Or ? = 2418 + 38 

Or ? = 2456 ≈ 2455
