Sum of first 12 numbers = (12 × 65) = 780 Sum of last 5 numbers = (76 × 5) = 380 Sum of 11th and 12th number = (780 - 380) = 400 So, 12th number = 400 × (7/20) = 140
Simplify the following expression:-
25% of (?) + (1/4)of 5600 = 2500 – 20% of 1940
Find the simplified of the following expression:
√324 + √576 = ?/ √9
6269 + 0.25× 444 + 0.8× 200 = ? × 15
...√? = 32% of 900 + 48% of 50
√(?) = (897 × 51) ÷ 1016.6
(5⁴) 5 × (25³)³=?
