Answer:

57 Years

Step-by-step explanation:

Preethi age = P Years

Father Age = 2.5 P

Mother : Grand Mother  are  5M & 9.3M

5M = 43

9.3M = (43/5)* 9.3 = 79.98 = 80 Years

GF : GM : P = 13F ,  12F  & 3 F

12 F = 80 Years

3F = 20 years

Preethi age = 20 Years

Father Age = 2.5 * 20 = 50 Years

Father age after 7 Years = 50  +  7 = 57 Years
