Question : 31 of 200

Marks: +1, -0

If 5 × 6 × 7 × 8 = 169, 5 × 7 × 9 × 11 = 256, then what will be the value for 6 × 9 × 12 × 15?

Solution:

(2)

Here, 5 × 6 × 7 × 8 means (5 +8) × (6 + 7) = 13^2 = 169

5 × 7 × 9 × 11 means (5 + 11) × (7+ 9) = 16^2 = 256

Similarly,

6 × 9 × 12 × 15 means (6+ 15) × (9 + 12) = 21^2 = 441
