Correct Answer: (3)
Solution: (3)
Sum of ages of A, B, C and D after 7 years $=(76+4 \times 7)$ Years $=104$ years
After 7 years $A: B: C: D=7: 6: 5: 8$
Sum of the terms of ratio $=7+6+5+8=26$
$\therefore$ C’s age after 7 years $=\left(\frac{5}{26} \times 104\right)$ years $=20$ years
$\therefore$ C’s present age $=13$ years
