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
