## Ratio and Proportion Aptitude Test Paper 416) Rs 7800 are distributed among A, B, and C. The share of "A" is the ¾ of the share of B, and the share of B is the 2/3 of the share of C. Find the difference between the share of B and C. - 1200
- 1300
- 1500
- 800
The share of A: B is 3: 4
i.e., A: B: C = 3*2: 4*2: 4*3 The difference between the share of B and C = 3600- 2400 = 1200 17) A bag contains Rs 410 in the form of Rs 5, Rs 2, and Rs 1 coins. The number of coins is in the ratio 4: 6: 9. So, find the number of 2 Rupees coins. - 40
- 50
- 60
- 70
ATQ, if the ratio of coins = 4: 6: 9 According to the given ratio, the ratio of amounts = 5*4: 6*2: 9*1 = 20: 12: 9 The total amount in the form of two rupees coins = 120 18) The ratio of copper and zinc in a 63 kg alloy is 4: 3. Some amount of copper is extracted from the alloy, and the ratio becomes 10: 9. How much copper is extracted? - 8kg
- 6kg
- 12kg
- 10kg
Amount of copper in alloy = [copper ratio/ sum of ratios]* total quantity of alloy Copper = {4/7}* 63 = 36 kg 19) The ratio of land and water on earth is 1: 2. In the northern hemisphere, the ratio is 2: 3. What is the ratio in the southern hemisphere? - 1:11
- 2:11
- 3:11
- 4:11
The ratio of land: water = 1: 2
i.e., the northern hemisphere is 50% of the total earth. We can say southern hemisphere = total area- northern hemisphere. To make the northern hemisphere 50% of the total area Subtract equation i by ii Hence, southern hemisphere = 10- 6: 20-9 = 4: 11 20) Vessels A and B contain mixtures of milk and water in the ratios 4: 5and 5: 1respectively. In what ratio should quantities of the mixture be taken from A and B to form a mixture in which milk to water is in the ratio 5: 4? - 2: 5
- 4: 3
- 5: 2
- 2: 3
Let the quantity of vessels A and B in the ratio x: y to form a mixture of water and milk in the ratio 4: 5. Now, ATQ quantities of the mixture should be taken from A and B.
