Question

If 3 men or 4 women can earn Rs. 480 in a day, find how much will 6 men and 11 women earn in a day?

Answer 1

Explanation:

SOLUTION

Earning of 3 men = earning of 4 women

=> Earning of 1 man = earning of 4/3 women

=> Earning of 6 men = earning of (4/3 × 6) women = earning of 8 women.

=> Earning of 6 men and 11 women = earning of (8 + 11) women = earning of 19 women.

Let 6 men and 11 women i.e. 19 women earn ₹x in a day.

Note that,

more women will earn more per day.

SO,

it is a case of direct variation.

=> 4/480 = 19/x

=> 4x = 19 × 480

=> x = 480 × 19/4

=> x = 2280

Hence,

6 men and 11 women will earn. ₹2280 in a day.
