Question
A vessel contains 320 litres of milk and water in the
ratio of 5:3. If 10 litres of milk is added to the mixture, then find the ratio of milk to water in the final mixture.Solution
The quantity of milk in the initial mixture = 320 Γ 5/8 = 200 litres The quantity of water in the initial mixture = 320 - 200 = 120 litres The ratio of milk to water in the final mixture = (200 + 10) : 120 = 210:120 = 7:4
What value should come in place of (?) in the given expression.
450 Γ· 9 + 75% of 160 β 64 Γ· 4 = ?
2/5 of 3/4 of 7/9 of 14400 = ?
7/3 of 4/5 of 15/56 of ? = 83
[564 + 32 of 18 Γ 9 Γ· 12 + 162 ] Γ· 4 = ?
What should come in place of (?) question mark in the given expression.
Β (25% of 320) + (3/8 of 400) β 30 = ?
45% of 360 - 160 + ? = β324
187 ÷ 5 ÷ 0.4 = ? – 24 × 2.4
Find the simplified value of the following expression:
[{12 + (13 Γ 4 Γ· 2 Γ· 2) Γ 5 β 8} + 13 of 8]
18 Γ 15 + 86 β 58 =? + 38
Β
√(24²+285-8²-172) = ?²
