The correct answer is B
74% of 2840 + 80% of 1640 - ?= 47²
121/? = ?/144
Find the value of the given expression.
? ÷ 62 × 12 = 264
180 ÷ 3 of 2 = 102 – ?
28(4/5) + 52(1/2) × 8(2/7) - 11(1/5) = ? + 6(1/5)
Evaluate: (936 ÷ 12) × (225 ÷ 15) − (144 ÷ 12) × 18
√10000 x √8100 - (50)² = √(?) + (80)²
Simplify the following expression:
(814-1)/82×80× (38+1)
(√784 ×20+ √4225 ×14)/(√1764 ×5) = ?
