A and B are employed in a work. A worked for 7 days and B worked for 5 days. Per day work of A and B is 2 units and 4 units respectively. Share of A out of total wages received by A and B is Rs. 4900. What is the share (in Rs.) of B?
Show answer & explanation
Correct answer: A
Explanation
Given:
A's efficiency = 2 units/day; Time = 7 days
B's efficiency = 4 units/day; Time = 5 days
Work done by A = 2 × 7 = 14
Work done by B = 4 × 5 = 20
Ratio = A : B = 14 : 20 = 7 : 10
A's share = 4900 ⇒ 7 parts = 4900
1 part = 700
B's share = 10 × 700 = 7000 Rupees
