Question
Aisha and Neel can complete a job alone in 66 days and 99
days respectively. Working together, they earn a total wage of Rs. 11,550. How much does Aisha receive?Solution
ATQ,
When the same work is done by two people, the ratio of efficiency is the reciprocal of the days taken by them.
Ratio of efficiency of Aisha and Neel respectively = 99:66 = 3:2
So, ratio of wages received by Aisha and Neel respectively = 3:2
Therefore, required wage = (3/5) × 11,550 = Rs. 6,930
What will come in place of the question mark (?) in the following questions?
?= √(4 × ∛(16 × √(4 × ∛(16 ×…… ∝)) ) )
560 ÷ 14 × 3 – 25 = ?
What value will come in place of (?) question mark in the given expression.
√144 × √81 + 7² – 5³ = ?
56 x 8 – 65% of 40 = ? + 14 x √625
3(2/3) of 2(5/11) of 5(2/5) of 75 = ?
18 × 15 + 86 – 58 =? + 38
What value should come in the place of (?) in the following questions?
222 + 322 – 508 = ? * 5
25.6% of 250 + √? = 119
