None of these
Solution:

∴ 26x = 26×3
⇒x=3
Required difference = 45 – 18 = 27 years

3
Solution:
Probability of selecting a Red flag is 1/4
Now, 1 → 4 flags
So, 4 → 16 flags
So, no. of black flags = 16 – (4 + 5)
= 7
Q4. The average of present age of A and B is 26 years if present age of C is also included their average age increases by 2 years. Find the ratio of ages of A to C.
4 : 5
6 : 7
7 : 5
3 : 4
Cannot be determined
Solution:
Present age of A and B = 26 × 2 = 52
A + B = 52 …(i)
Present age of A, B and C = 3 × (26 + 2) = 84
A + B + C = 84 …(ii)
Present age of C = 84 – 52 = 32
Ratio of A to C cannot be determined.
