Question

One number is 5/2 times as large as another. the sum of number is 28. find the number ​

Answer 1

Let one no. be x

So x×5/2=y

x+y=28

y=28-x

5x/2=28-x

Multiply EQN by 2

so,

5x=56-2x

7x=56

x=8

So no.is 40/2=20

and other no is 8

Answer 2

•Let Another No. Be x

•ATQ , Other no. = 5/2x

•So ,Given

♤x+5/2x = 28

♤2x+6x/2=28

♤8x=56

♤×=56/8

♤×=7

■ x=7

& ■5/2x=5/2×7=35/2=17.5
