Question

Mrs rohit gave a total of 64.90 dollars to her three sons.eldest son received 4.30 more from youngest son, second son received 7.8 less from youngest son. How much does an eldest son received?

Answer 1

Step-by-step explanation:

Total amount =64.90

let the youngest son's amount=x

Then elder's amount =x+4.30

second son's amount =x-7.80

calculating for the youngest son:

x+x+4.30+x-7.80=64.9

3x=68.4

×=22.8

Hence the youngest son had 22.8

elder's amount=x+4.30

=22.8+4.30

=27.1
