Question

If 5 men or 7 women can earn rs 525 per day how much would 10 men and 13 women will earmm per day?

Answer 1

by given
5 * men = 525
men = 525/5 =105 ---------@1
similarly 7*women =525
women = 525/7 =75-------@2
from @1 and @2
10 * men = 10 *105 = 1050
13 *women = 13*75 = 975

therefore
10*men + 13*women = 1050 +975 =2025
hope it helps

Answer 2

let men be x

5x=525
x=525/5=105
1 men salary per day is 105

let women be y
7y=525
y=525/7=75
salary of one women is 75

10x+7y
10(105)+13(75)=2025
