Question

The ratio of the present ages of Hari and Harry is 5 : 7. Four years later the ratio of their ages will be 3 : 4. Find their present ages. हरि और हैरी की वर्तमान आयु का अनुपात 5: 7. है। चार साल बाद उनकी आयु का अनुपात 3: 4 होगा। उनकी वर्तमान आयु ज्ञात कीजिए।​

Answer 1

Step-by-step explanation:

Let the ages Of Hari and Harry is 5x and 7x respectively.

After Four years,

Their ages will be (5x +4) and (7x + 4) respectively.

A/Q

Ratio of their age after 4 years = 3/4

$= > ((5x + 4) \div (7x + 4)) = 3 \div 4$

$= > 4(5x + 4) = 3(7x + 4) \\ = > 20x + 16 = 21x + 12 \\ = > 21x - 20x = 16 - 12 \\ = > x = 4$

So , their current ages of HARI and HARRY is 5x = 5×4 = 20 years and 7x = 7×4 = 28 years respectively
