Question
A mixture contains milk and water in the ratio 3 : 5. If
the total quantity is 40 litres, how much milk should be added to make the ratio 1 : 1?Solution
Given: A mixture contains milk and water in the ratio 3 : 5. If the total quantity is 40 litres. Solution: Total parts = (3 + 5 = 8) Total quantity = 40 litres 
To make the ratio 1 : 1, milk must equal water. Water remains 25 L, so milk should also be 25 L. Milk to be added: 25 - 15 = 10 L So, 10 L milk should be added to make the ratio 1 : 1. Thus, correct option is (b).
What will come in the place of question mark (?) in the given expression?
(√? - 17) X 40 + 145 = 1000 - 15
- Evaluate: 195 ÷ 13 × 8 + 220 – 30% of 500
What will come in the place of question mark (?) in the given expression?
23 X 35 - ? = (132 + 16) X 3 + 25
- Simplify the following expression:
(7 ÷ 0.125) x (10 ÷ 10/3 ) = ?
Simplify the following expressions and choose the correct option.
512 ÷ 2⁴ + 3³ × (5² − 4²) = ?
{5% of (20 × 25) + 6% of (30 ×35)} ÷ 11 = ?
30 of 20 - 40 + 182 - 23 × ? = 83
