Question
12 engineers complete designing 180 blueprints in 15
days. If the goal is to complete 270 blueprints in 18 days, how many engineers are required?Solution
ATQ,
Let the required number of engineers be ‘w’ and let efficiency of each engineer be ‘M’ units per day
(12 × 15 × M) ÷ 180 = (18 × w × M) ÷ 270
So, w = 15
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
?% of 399.97 = 11.982 + 16.13 × 4.16 – 35.99
(2220.23 ÷ 36.98) + (768.32 ÷ 23.9) + 1644.11 = ?

`root(3)(725.87)` `-:` `sqrt(81.033)` Â + 49.88% of 809.77 = ? - (14.78Â `xx` Â 52.2)
? = (5.8)2 + (8.9)2 + (4.7) 2 + 24.7% of 20
(1177.99 + 226.99 + 94.923) ÷ 24.97% of 59.989 = ?
11.06 2 – 7.12 × 4.88 + 9.96 = 12.22 × ?Â
