Question
A water tank has a length of 40 metres, width of 20 metres,
and height of 15 metres. If each water block takes up 200 m³, how many such blocks can the tank accommodate?Solution
ATQ,
Volume of the tank = length × breadth × height = 40 × 20 × 15 = 12000 m³
So, number of water blocks the tank can accommodate = 12000 ÷ 200 = 60
31% of 1900 - ? = 73
(√784 ×20+ √4225 ×14)/(√1764 ×5) = ?
√196 + (0.25 × 144) + 19 = ? + 72
Select the correct combination of mathematical signs that can sequentially replace the * signs and balance the given equation.
42 * 7 * 64 * 11 * 6 *4
44% of 1900 + 25% of ? = 9000
What will come in the place of question mark (?) in the given expression?
√64 X 9 ÷ 3 + 12 X 3 = ? + 363/7 Of 504 ÷ 12 + 17 = √?
13 X √? + 256 ÷ 4 = 30% of 900 - 50
32 × 3 (54 – 15) + 186 ÷ 3 ÷ 2 – (21)² = ?
