Q1
The income of Neha and Hitesh are in the ratio of 4:5 and their expenditure is in the ratio of 2:3. If each of them saves 2000, then find their income.
- A. 4000, 6000
B. 4000, 5000
C. 5000, 4000
D. 5000, 6000
4x – 2y = 2000 and 5x – 3y = 2000.
X = 1000, so income = 4000 and 5000
X = 1000, so income = 4000 and 5000
Q2
A bag contains 25p coins, 50p coins and 1 rupee coins whose values are in the ratio of 8:4:2. The total values of coins are 840. Then find the total amount in rupees.
- A. 220
B. 240
C. 260
D. 280
Value is given in the ratio 8:4:2.
[latex](\frac {8x}{0.25}) + (\frac {4x}{0.5}) + (\frac{2x}{1})[/latex] = 840
X = 20. Total amount = 14*20 = 280
[latex](\frac {8x}{0.25}) + (\frac {4x}{0.5}) + (\frac{2x}{1})[/latex] = 840
X = 20. Total amount = 14*20 = 280
Q3
The sum of three numbers is 210. If the ratio between the first and second number be 2:3 and that between the second and third be 4:5, then the difference between the first and third number?
- A. 21
B. 35
C. 42
D. 56
a: b = 2:3 and b:c = 4:5
a:b:c = 8:12:15
Difference between first and third number = [latex]\frac {7}{35} \times[/latex] 210 = 42
a:b:c = 8:12:15
Difference between first and third number = [latex]\frac {7}{35} \times[/latex] 210 = 42
Q4
The ratio of two numbers is 3:4. If 3 is subtracted from both the numbers, the ratio becomes 1:2. Find the sum of the two numbers?
- A. 9
B. 10.5
C. 11.5
D. 12
(3x – 3)/(4x – 3) = [latex]\frac {1}{2}[/latex]
x = 1.5
sum of the numbers = 7 × 1.5 = 10.5
x = 1.5
sum of the numbers = 7 × 1.5 = 10.5
Q5
A vessel contains milk and water in the ratio of 4:3. If 14 litres of the mixture is drawn and filled with water, the ratio changes to 3:4. How much milk was there in the vessel initially?
- A. 24
B. 32
C. 40
D. 48
Milk = 4x and water = 3x
Milk = 4x – 14 × [latex]\frac {4}{7}[/latex] and water = 3x – 14 × [latex]\frac {3}{7}[/latex] + 14
4x – 8: 3x + 8 = 3:4
X = 8, so milk = 8 × 4 = 32 litres
Milk = 4x – 14 × [latex]\frac {4}{7}[/latex] and water = 3x – 14 × [latex]\frac {3}{7}[/latex] + 14
4x – 8: 3x + 8 = 3:4
X = 8, so milk = 8 × 4 = 32 litres
