1 boy 1 day=70/7=10/-
15 boys 1 days=10*15=150/-
15 boys 6 days=150*6
= 900/-
1 boy 7 days = 840/12=70/-
1 boy 1 day=70/7=10/-
15 boys 1 days=10*15=150/-
15 boys 6 days=150*6

let take the half of 840 Rupees = 420 rupees
let take the half of 12 Boys = 6
= 6 Boys earn in 7 days = 420 Rupees
= 3 Boys = 210 Rupees .
so, we add 12 + 3 = 15 Boys
& we add 840 + 210 = 1050
15 boys earn 1050 rupees in 7 days
70 - 1050 = 980 rupees in 6 days
because 1 boy earn in 7 days = 70
let take the half of 12 Boys = 6
= 6 Boys earn in 7 days = 420 Rupees
= 3 Boys = 210 Rupees .
so, we add 12 + 3 = 15 Boys
& we add 840 + 210 = 1050
15 boys earn 1050 rupees in 7 days
70 - 1050 = 980 rupees in 6 days
because 1 boy earn in 7 days = 70
