Answer 1

So age of Anup’s father will be (100 – x) years

The age of Anuj is (100-x)/5 years

So, When Anup is as old as his father after (100 – 2x) years,

Then Anuj’s age = present age of his father (Anup) + 8

Present age of Anuj + 100 – 2x = Present age of Anup + 8

So,

(100 – x)/5 + (100 – 2x) = x + 8

(100-x)/5 – 3x = 8 – 100

(100 – x – 15x)/5 = -92

By cross-multiplying we get,

100 – 16x = -460

-16x = -460 – 100

-16x = -560

x = -560/-16 = 35

∴ Present age of Anup is 35 years then,

Age of Anup’s father will be (100-x) = 100-35 = 65 years

The age of Anuj is (100-x)/5

(100 – 35)/5

= 65/5 = 13 years.

_______________________________________________

sabse pahle Anup ke father ka age(100 - x) yrs..

then Anuj ho jayega (100 - x)/5 years

according to question Anup is old as his father after (100 - 2x) years

then Anuj age ho jaega (present age of Anup father + 8 )

so present age of Anuj + 100 - 2 x is equal to present age of Anup + 8 hoga...

Uske bad main solution nikala h aap dekh lo

Fir cross multiplying

Fir aapka x ka value aaJaega 35 ...

mans Anup ka age Ho Gaya 35 years

And uske father ka age Ho Gaya (100-x)/5 = (100-35)/5= 13 yrs...
