Hey!
I'm sorry but if you don't mind I will answer the question in English.

Firstly, let's mark people from the question as symbols and write down what we know:

Grandfather - G      Father - F      Child - C

We know that:

We assume that:

1 year = 12 months ≈ 52 weeks = 365 days
1 week = 7 days
1 month ≈ 4.25 weeks ≈ 30 days

Knowing that, we can make the following calculation:

We said that: 1 week = 7 days therefore, we can write:

It is not enough to solve the problem though, we need another part of the equation. Let's try with the grandfather:

Now we should bring everything to the same unknown - days

Let's try putting it together now:

I hope that it helps :)

Cheers!

पोता का उम्र सालों में = P
बाप का उम्र सालों में = B
दादा का उम्र  सालों में  = D
कुल मिलाकर हुआ              P+B+D = 140  साल

पोते का उम्र  महीनों में = P* 12  =  दादा का उम्र सालों में = D

पोते का उम्र सप्ताहों में = P * 52
पोते का उम्र दिनों में = P * 52 * 7   = बाप का उम्र सप्ताहों में =   B * 52
B = 7 * P

तब  कुल मिलाकर :    P+B+D =  P + 7*P + 12*P =  140
=>   20 P = 140      ==>    P = 7

तब  हुआ :        पोता  7 साल का,    बाप है  49 सालों का,     दादा है   84 साल का
