Question
130 litres of a mixture contains 35% milk and rest
water. If ‘x’ litres of milk is added into the mixture then quantity of water in the final mixture becomes 50% of total quantity of mixture. Find the value of ‘x’.Solution
Quantity of milk in the initial mixture = 130 × 0.35 = 45.5 litres Quantity of water in the initial mixture = 130 – 45.5 = 84.5 litres Quantity of water is unchanged in the final mixture. So, Quantity of final mixture = (84.5/50) × 100 = 169 litres Quantity of milk in final mixture = 169 – 84.5 = 84.5 litres Value of ‘x’ = 84.5 – 45.5 = 39
What will come in the place of question mark (?) in the given expression?
(63 - ?) ÷ 5 + √625 = 19 X (9 - 6)
- What will come in place of (?), in the given expression.
(4² + 6²) × 2 = ? What will come in the place of question mark (?) in the given expression?
(40/25) X 80 - ? = 45% of 300 - 5525.6% of 250 + √? = 119
1220 ÷ 61 ÷ 5 + 450 of 20% - 70 = √ ?
Simplify the expression:
(5x + 15) / (x² + 3x)
What will come in the place of question mark (?) in the given expression?
435 ÷ 29 X 792 ÷ 44 = √(? + 14) + 35 + 221 ÷ 17
...192.251 + 326.233 + 125.021 + 19.273 = ?
36% of 640 – 12.5% of 352 + 25% of 640 = ? – 48% of 432
Simplify the following expressions and choose the correct option.
18 * 15 - {3/5 of 250 + 72}
