Question
A mixture contains ‘x’% milk. 20% of this mixture is
taken out and is replaced with same quantity of water. This procedure is repeated two more times. If the resultant mixture contains 35.84% milk, then find the value of ‘x’.Solution
According to question, => 35.84 = x × (8/10) × (8/10) × (8/10) => x = 70
40 × 55.96 ÷ 7 – 20% of 699.81 + 63 = ? - (11479.50 ÷ 7)
What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)...
11.67 × 50.23 + ? = 14.88% of 600.44 + 9.66 × 8.272
What approximate value will replace the question mark (?) in the following?
? = 1...
(56.03 + 112.98) ÷ 13.211 = 89.9 – 25.23% of ?
? + 163.99 – 103.01 = 24.01 × 6.98
78% of 1450 + 26² = ? + 1323 ÷ 17
