Question

If 4 × 24 = 6, 2 × 8 = 4, 1 × 3 = 3, then find the value of 7 × 21?

• A. 42
• B. 3
• C. 63
• D. 21

Answer 1

Answer:

B. 3

The logic is:

$4\times{24}$ = 6 → $24\div{4}=6$

$2\times{8}=4$ → $8\div{4}=2$

$1\times{3}=3$ → 3 $\div$ 1 = 1

Similarly,

7$\times{21}$ ? → 21 $\div$ 7 = 3

Hence, ‘3’ is the correct answer
