Question
N workers can complete a piece of work in 50 days. When
5 more workers joined, then the work got completed in 40 days, then what is the value of N?Solution
As we know, M1 × D1 = M2 × D2 Where, M = number of Men and D = number of Days ⇒ N × 50 = (N + 5) × 40 ⇒  5N = 4N + 20 ⇒  N = 20 Hence, the value of N = 20
1080.04 – 330.18 + 449.98 ÷ 15.06 = ?
Solve the given equation for ?. Find the approximate value.
[(49.88% of 320.11) × (34.85% of 460.24)] ÷ √783.94 = ?
(2310.23 ÷ 32.98) + (1008.32 ÷ 23.9) + 1594.11 = ?
2090.03 ÷ 54.98 x 49.9 = ? + 20.32
(32.15)2 – (255.89)(1/2) – (10648.08)(1/3) = ?

(44.79 × 74.21) ÷ (11.862 – 33.12) + 37.48% of ? = 180.23
54.8% of 800 - √(?) = 33.98% of 400 – 12.42% of 300
5 (1/2)% of 3599.67 + {18.11% of 2499.67} + √255.11 - 10% of 1799.99 - (63.01 – 47.08) = ?
