Answer 2

8.

Let, the smaller number be x

so, the greater one will be 3x

by given condition

x+3x=124

4x = 124

x = 124/4

x = 31

the 2 numbers are 31 and 93

9.

let, smaller number be x

so, the other will be 5x

by given condition,

5x-x=132

4x = 132

x = 132/4

x= 33

so ,the numbers are 33 and 99.

10.

let, the 2 consecutive even numbers be 'x' and 'x+2'.

by given condition,

x+x+2 = 74

2x = 72

x = 36

the 2 consecutive numbers are 36 and 38.
