Answer 1

Answer:

Age of Arpita=4x=4×8=32years

Age of Bina = 7x =7×8=56years

Step-by-step explanation:

Ratio of ages of Arpita and Bina =4:7

Let common factor =x

Present Age of Arpita= 4x

Present Age of Bina =7x

8years ago,

Age of Arpita =4x-8

Age of Bina =7x - 8

Ratio of ages = 1:2

According to question

4x-8/7x-8 = 1/2

2(4x-8) = 1(7x-8)

8x-16=7x-8

8x-7x= -8+16

x=8

Present Ages

Arpita= 4×8=32years

Bina =7×8 = 56years
