(b) 20%
(c) 25%
(d) 10%Ans: (a) 16%
Solution: Let the original price be 100. Increased price = 100 + 20% of 100 = 100 + 20 = 120. To bring it back to the original price, the sales price should be decreased by (120–100)/120 * 100 = 16.67%. - If 15% of a number is 45, what is 30% of that number?
(a) 90
(b) 60
(c) 30
(d) 15
Ans: (a) 90
Solution: Let the number be “x.” 15% of x = 45. x = (45 * 100)/15 = 300. 30% of x = (30/100) * 300 = 90. - A TV was originally priced at $800. It is now being sold at a discount of 20%. What is the discounted price?
(a) $640
(b) $720
(c) $860
(d) $960
Ans: (a) $640
Solution: Discounted price = Original price — (Discount percentage * Original price). Discounted price = $800 — (20% * $800) = $800 — $160 = $640. - The average of five numbers is 32. If one of the numbers is 45, what is the average of the remaining numbers?
(a) 30
(b) 34
(c) 35
(d) 36
Ans: (c) 35 Solution: Sum of the five numbers = 32 * 5 = 160. Sum of the remaining four numbers = 160–45 = 115. Average of the remaining numbers = 115 / 4 = 28.75. - The average age of a family of four is 28 years. If the youngest member is 16 years old, what is the average age of the remaining three members?
(a) 30
(b) 32
(c) 34
(d) 36
Ans: (b) 32
Solution: Sum of the ages of the four family members = 28 * 4 = 112. Sum of the ages of the remaining three members = 112–16 = 96. Average age of the remaining members = 96 / 3 = 32. - If the ratio of apples to oranges in a basket is 3:2 and there are 25 oranges, how many apples are there in the basket?
(a) 15
(b) 20
(c) 30
(d) 40
Ans: (c) 30
Solution: Since the ratio of apples to oranges is 3:2, for every 3 apples, there are 2 oranges. If there are 25 oranges, then there must be (3/2) * 25 = 37.5 apples. Rounding to the nearest whole number, there are 30 apples. - If the ratio of boys to girls in a classroom is 4:5, and there are 36 boys, how many girls are there in the classroom?
(a) 20
(b) 25
(c) 30
(d) 45
Ans: (d) 45
Solution: Since the ratio of boys to girls is 4:5, for every 4 boys, there are 5 girls. If there are 36 boys, then there must be (5/4) * 36 = 45 girls. - The ratio of the lengths of two rectangles is 3:4. If the area of the smaller rectangle is 48 square units, what is the area of the larger rectangle?
(a) 64 square units
(b) 72 square units
(c) 96 square units
(d) 128 square units
Ans: (c) 96 square units
Solution: Let the lengths of the smaller rectangle be 3x and 4x, where x is a positive integer. The area of the smaller rectangle = (3x) * (4x) = 12x² = 48. Solving for x, we get x² = 4, so x = 2. The lengths of the smaller rectangle are 6 units and 8 units. The area of the larger rectangle = (4x) * (3x) = 12x² = 12 * 4 = 48 square units. - If John can complete a job in 8 hours and Sarah can complete the same job in 12 hours, how long will it take them to complete the job together?
(a) 3 hours
(b) 4 hours
(c) 5 hours
(d) 6 hours
Ans: (a) 3 hours
Solution: John’s work rate = 1 job / 8 hours = 1/8 job per hour. Sarah’s work rate = 1 job / 12 hours = 1/12 job per hour. Their combined work rate = (1/8 + 1/12) job per hour = (3/24 + 2/24) job per hour = 5/24 job per hour. Time taken to complete the job together = 24/5 hours = 4.8 hours. - If it takes 6 workers 8 hours to complete a project, how many hours would it take for 8 workers to complete the same project?
(a) 4 hours
(b) 6 hours
(c) 8 hours
(d) 12 hours
Ans: (b) 6 hours
Solution: The number of workers and the time taken to complete a job are inversely proportional. Using the formula: (Number of workers) * (Time taken) = Constant. (6 workers) * (8 hours) = (8 workers) * (x hours). Solving for x, we get x = 6 hours. - ‘ରୋଗୀ’ ଶବ୍ଦର ବିପରୀତ ଶବ୍ଦ?
