Question

If alice deserves twice as many marks as brenda and brenda deserves half as many marks as catherine how many does each receive when their total marks are 125?

Answer 1

Answer:

let Catherine deserves x marks

then brenda deserves x/2marks

and Alice deserves 2 × x/2= x marks

then the required equation is :

x + x/2 + x= 125

5x/2=125

x= 125 ×2/5

x= 50marks

hence Catherine deserves 50marks

Brenda deserves 25marks

and Alice deserves 50marks
