Question

12 women and 8 boys can earn Rs 13640 in 11 days,
6 women and 10 boys can earn Rs 13800 in 15 days,
In How many days will 10 women and 15 boys can rs 8700​

Answer 1

6 days will (10 women + 15 boys ) can Rs. 8700

(12 women + 8 boys ) do work 11 days to earn 13640 Rs.

or,(12 women + 8 boys ) do work 1 day to earn 13640/11 = 1240

i.e., (12 women + 8 boys) = 1240..

.(1). [ here I compare salary of women and boys to price not the number of them ]

again, (6 women + 10 boys ) do work 15 days to earn 13800 Rs.

or, (6 women + 10 boys ) do work 1 day to earn 13800/15 = 920 Rs.

i.e., (6 women + 10 boys) = 920..... (2)

from equations (1) and (2),

20boys - 8boys = 2 × 920 - 1240

⇒12 boys = 1840 - 1240 = 600

⇒1 boys = 50Rs .

1 boy salary = 50 Rs/day

1 woman salary = (1240 - 8 × 50)/12

= (1240 - 400)/12 = 70 Rs.

so, (10 women + 15 boys ) = 10 × 70 + 15 × 50 = 700 + 750 = 1450 Rs/day

then, number of days = 8700/1450 = 6 days
