Two numbers are such that the ratio between them is 3 : 5. If each is increased by 10, the ratio between the new numbers so formed is 5 : 7 . Find

the original numbers. i need it with prper steps.for my exam

Let two nos. be 3x and 5x.

now, If each is increased by 10, then

thus, the nos. are 3x = 15 and 5x= 25

  • 11

LET ONE NUMBER BE X.

ANOTHER NUMBER BE X+10.

X/X+5 =3/5

THEN,

X+10/X+15=5/7

7(X+10) = 5(X+5)

70X+70+25X+25

45X=50

X=40/45

X=8/9
