Answer 2

Answer: 1) 16/3 , 2) 17/5 , 5) -15/17 , 6) 52/11 c.m. ,9)5 , 7) age of Sita = 14.25 years and age of Sita's Father = 42.75 years , 8) 74 , 10) 15 years , 11) 12 and 18 , 12) 3/5 , 3) -29/3.

4) Let 3 consecutives are x , (x+1) , (x+2).

There sum is “ 3x +3 ".

Now, (3x +3) × 7 = 63 => x = 2.

10) Let Present age of Sanjay = x

After 18 years his age = x+18

Before 4 year's his age = x-4

According to question, 3(x-4) = x+18 => x = 15 .

Hence, Present age of Sanjay is 15 years.

3) Let, the number subtracted is x.

According to question, (-8/3 ×3) - x =5/3

=> x = -29/3.
