Question

Sara's mark in maths is 15 more than in french .the total she scored in both subjects is 125.find how much she scored in each subjects.

Answer 1

Answer:

Let her marks in French be " x " and maths be " x + 15 "

Total marks = 125

or, x + x + 15 = 125

or, 2x + 15 = 125

or, 2x = 125 - 15

or, 2x = 110

or, x = 55

Maths marks = x + 15 = 55 + 15 = 70

French marks = x = 55
