Question

the sum of the two numbers is 2490 .if 6.5%of one number is equal to 8.5% of the others.find the numbers

Answer 1

$let \: \: the \: \: numbers \: \: be \: \: x \: \: and \: \: y \\ given \: \: \: x + y = 2490 \\ 0.065x = 0.085y \\ 0.065x = 0.085 \times (2490 - x) \\ 0.15x = 211.65 \\ x = 1411 \\ therefore \: \: y = 2490 - 1411 = 1079$

Answer 2

Answer:

sum of two numbers=2490

x+y=2490

6.5x%+8.5x%=2490

15x/100=2490

15x=2490*100

x = 2490*100/15

= 166*100

= 16600

1st number= 6.5%x

= 6.5/100*16600

= 1079

2nd number=8.5%x.

= 8.5/100*16600

= 1411
