1If the price of urea fertilizer is increased by 25%, by how much percent must a farmer reduce its consumption so that his total expenditure remains unchanged?
A.20%
B.25%
C.15%
D.30%
Explanation: Let the original price be 100 and consumption be 100. New price becomes 125. To keep expenditure constant at 10,000, new consumption must be 10,000 / 125 = 80. Therefore, the reduction in consumption is 20%.
2A farm machine is sold at a profit of 10%. If it had been bought for 10% less and sold for Rs. 30 more, the gain would have been 25%. Find the cost price of the machine.
A.Rs. 1,200
B.Rs. 1,500
C.Rs. 1,800
D.Rs. 2,000
Explanation: Let the cost price (CP) be 100x. Selling price (SP) is 110x. New CP is 90x. New SP with 25% profit is 90x * 1.25 = 112.5x. The difference is 112.5x - 110x = 2.5x. Since 2.5x = 30, x = 12. Thus, the original CP is Rs. 1,200.
3The average paddy yield of 10 experimental plots is 15 quintals. If the highest and lowest yields are excluded, the average yield of the remaining plots is 14.5 quintals. If the highest yield is 22 quintals, what is the lowest yield?
A.6 quintals
B.8 quintals
C.10 quintals
D.12 quintals
Explanation: Total yield of all 10 plots = 150 quintals. Total yield of the 8 plots after excluding highest and lowest = 8 * 14.5 = 116 quintals. The sum of the highest and lowest yields = 150 - 116 = 34 quintals. If the highest is 22 quintals, the lowest is 34 - 22 = 12 quintals.
4Two varieties of liquid organic fertilizer containing nitrogen and phosphorus in ratios 2:1 and 3:1 are mixed in the ratio 1:2. What is the ratio of nitrogen to phosphorus in the final mixture?
A.11:5
B.13:5
C.15:7
D.17:9
Explanation: Let us take 12 units of the first and 24 units of the second fertilizer. In the first (12 units), nitrogen = 8, phosphorus = 4. In the second (24 units), nitrogen = 18, phosphorus = 6. Total nitrogen = 8 + 18 = 26, total phosphorus = 4 + 6 = 10. The ratio is 26:10, which simplifies to 13:5.
5A farmer borrowed Rs. 15,000 from a cooperative bank at a simple interest rate of 8% per annum. How much total amount will he pay to clear the debt after 3 years and 6 months?
A.Rs. 18,200
B.Rs. 19,200
C.Rs. 20,400
D.Rs. 19,800
Explanation: Simple Interest (SI) = (P * R * T) / 100. Time = 3.5 years. Interest = (15000 * 8 * 3.5) / 100 = Rs. 4,200. Total amount to be repaid = Principal + Interest = 15000 + 4200 = Rs. 19,200.
6What will be the compound interest on a sum of Rs. 20,000 for 2 years at a rate of 10% per annum, compounded annually?
A.Rs. 4,000
B.Rs. 4,100
C.Rs. 4,200
D.Rs. 4,400
Explanation: Amount A = P * (1 + R/100)^T = 20000 * (1 + 10/100)^2 = 20000 * 1.21 = Rs. 24,200. Compound Interest (CI) = A - P = 24200 - 20000 = Rs. 4,200.
7A mechanical excavator can dig a pond in 12 days, while another excavator can dig the same pond in 15 days. If both machines work together, how many days will they take to complete the excavation?
A.6.22 days
B.7.15 days
C.6.67 days
D.5.85 days
Explanation: Work rate of the first machine = 1/12 per day. Work rate of the second machine = 1/15 per day. Combined rate = 1/12 + 1/15 = 9/60 = 3/20. Total days needed = 20/3 = 6.67 days.
8A tractor travels at a constant speed of 18 km/h. How much distance in meters will the tractor cover in exactly 20 minutes?
A.5,000 meters
B.6,000 meters
C.7,500 meters
D.4,500 meters
Explanation: Speed of 18 km/h is equal to 18 * (1000 / 3600) = 5 meters per second. Time is 20 minutes = 20 * 60 = 1200 seconds. Distance covered = speed * time = 5 * 1200 = 6,000 meters.
9Which of the following is the least natural number that must be added to 1056 so that the sum is completely divisible by 23?
A.2
B.3
C.18
D.21
Explanation: Dividing 1056 by 23 yields 1056 = 23 * 45 + 21, leaving a remainder of 21. To make it completely divisible, the least number to be added is 23 - 21 = 2.
10The Highest Common Factor (HCF) of two numbers is 11 and their Least Common Multiple (LCM) is 7700. If one of the numbers is 275, find the other number.
A.279
B.308
C.318
D.440
Explanation: Using the relation Product of two numbers = HCF * LCM. The other number = (11 * 7700) / 275 = 7700 / 25 = 308.
