Question
Two mixtures, P and Q, have milk-to-honey ratios of 7:5 and
8:9, respectively. When these two mixtures are combined, the total quantity of the final mixture becomes 0.84 liters, with the milk-to-Honey ratio in the final mixture being 37:33. What was the original quantity of mixture Q before mixing?Solution
ATQ;
Let quantity of milk and honey in mixture P and Q is 7x ml and 5x ml and 8y ml and 9y ml respectively.
Quantity of milk in 840 ml of mixture = 37/70 Γ 840 = 444 ml
Quantity of Honey in 840 ml of mixture = 840 β 444 = 396 ml
So, 7x + 8y = 444
And, 5x + 9y = 396
Solving above equations we get;
x = 36 and y = 24
So, quantity of mixture Q = 24 Γ 17 = 408 ml
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
