Answer 1

$\bf{\underline{\underline{Question:-}}}$

the ages of hari and abhi are in the ration 5:7 for year from new the ratio of their ages will be 3:4 find the present ages

$\bf{\underline{\underline{Solution:-}}}$

Let

• the common ratio be x.

So,

• age of Hari = 5x
• and age of Abhi = 7x

$\bf{\underline{\underline{After\:4\:years\:ago:-}}}$

→ age of Hari = 5x + 4

→ and age of Abhi = 7x + 4

$\bf{\underline{\underline{According\:To\: Question:-}}}$

→$\sf \dfrac{(5x+4)}{(7x+4)}= \dfrac{3}{4}$

→$\sf 4(5x+4) = 3(7x+4)$

→ $\sf20x + 16 = 21x + 12$

→ $\sf 20x - 21x = 12 - 16$

→$\sf -1x = -4$

→ $\sf x = 4$

$\bf{\underline{\underline{Hence:-}}}$

• present age of Hari = 5x = 5 × 4 = 20
• present age of Abhi = 7x = 7 × 4= 28
