Total work done by 28 men and 40 women is equal Therefore, efficiency of men and women 28 × M × 20 = 40 × W × 28 M : W = 2 : 1 Let Total work = 28 × 2 × 20 = 1120 unit Work done by 20 men and 12 women in 16 days = (20 × 2 + 12 × 1) × 16 = 832 unit Remaining work = 1120 – 832 = 288 unit Total Efficiency (inclusive of 20 women) = 52 + (20 × 1) = 72 Remaining work done in = 288/72 = 4 days
(22² × 8²) ÷ (92.4 ÷ 4.2) =? × 32
{(123 + ? × 28) – 1254} × (2328 ÷ 97 – 13) = 8195
Solve for ?.
?² = 37% of 800 – 14 × 18+ 5! - 20
6612 ÷ 19 - ?% of 240 = -2196
(1/8) × (256 × 2)/(8 × 4) + ?3 = 1730
Simplify the following expression:
84 - [21 - {14 - (25 - 16 + 8) }] ÷ 3 X 6
4? + 82 = 22% of 300
779 + 136 – 334 = 270 + 121 + ?
