correct answer is: option a (48)
Explanation: The relationship between 20 and 30 can be expressed as: $20 \times \frac{3}{2} = 30$. We need to find a number that, when multiplied by $\frac{3}{2}$, equals 72. Thus, the required number is $72 \div \frac{3}{2} = 72 \times \frac{2}{3} = 48$.

• Option a: 48 is the correct answer because $48 \times \frac{3}{2} = 72$.
• Option b: 19 is incorrect as $19 \times \frac{3}{2} \neq 72$.
• Option c: 20 is incorrect as $20 \times \frac{3}{2} \neq 72$.
• Option d: 31 is incorrect as $31 \times \frac{3}{2} \neq 72$.

correct answer is: option a (KPND)
Explanation: The pattern is that each letter is shifted by +6 places in the alphabet. R + 6 = W, I + 6 = D, G + 6 = B, T + 6 = Y. Following the same pattern, F + 6 = K, U + 6 = P, S + 6 = N, Y + 6 = D.

• Option a: KPND is the correct answer as it follows the +6 shift pattern.
• Option b: LPND is incorrect as it doesn't follow the pattern.
• Option c: KPNB is incorrect as it doesn't follow the pattern.
• Option d: LMPB is incorrect as it doesn't follow the pattern.
