Answer: 8 : 9 : 12
Explanation Given: g : h = 8 : 9 h : i = 9 : 12 To find the combined ratio g : h : i, we need to make the ratio of h the same in both. g : h = 8 : 9 h : i = 9 : 12 Since h has the same ratio in both (9), we can directly combine: g : h : i = 8 : 9 : 12

Answer: 36
Explanation A perfect square is a number that can be expressed as the product of an integer multiplied by itself. Out of the given options : 18 is not a perfect square because it cannot be expressed as the product of an integer multiplied by itself. 27 is not a perfect square because it cannot be expressed as the product of an integer multiplied by itself. 30 is not a perfect square because it cannot be expressed as the product of an integer multiplied by itself. 36 is a perfect square because it can be expressed as 6×6=36, where 6 is an integer.
Answer: 5
Explanation To solve this proportion, we can use the following steps: Write the proportion as a fraction: 3/x = 12/20 Cross-multiply: 3 × 20 = 12 × x Simplify: 60 = 12x Divide both sides by 12: x = 60/12 Simplify: x = 5 So, the value of x is 5.
Answer: 40 km
Explanation Distance is directly proportional to speed when time is constant (12 : 9 = 4 : 3). Solving the ratio gives the original distance as 30 km, so the increased distance is 30 + 10 = 40 km .
Answer: 7:10
Explanation a:b = 7:8 b:c = 4:5 Make b same: a:b = 14:16 b:c = 16:20 Therefore, a:c = 14:20 = 7:10 . Last verified on 14-05-2026
Answer: 153600
Explanation 1. The ratio of length to breadth is 3:2. Let's assume the length is 3x and the breadth is 2x. 2. The perimeter of the rectangular park is 2(3x + 2x) = 10x. 3. The man completes one round in 8 minutes at a speed of 12 km/hr. Convert the speed to meters per minute: 12 km/hr = 12,000 m/60 min = 200 m/min 1. The distance covered in 8 minutes is: 200 m/min × 8 min = 1600 m Since the man completes one round, the perimeter of the park is 1600 m: 10x = 1600 x = 160 Now, find the length and breadth: Length = 3x = 3 × 160 = 480 m Breadth = 2x = 2 × 160 = 320 m Finally, calculate the area: Area = Length × Breadth = 480 × 320 = 153,600 sq. m
Answer: 24000
Explanation Calculating the Ratio of Capitals Asad : Aamir = 63000 : 72000 = 7 : 8 Calculating the Profit Share Total parts = 7 + 8 = 15 Aamir's share = 8/15 × 45000 = 8 × 3000 = 24000
Answer: 3:10
Explanation Make b the same in both ratios a:b = 3:4 b:c = 2:5 → multiply by 2 → b:c = 4:10 Now a:b:c = 3:4:10 So a:c = 3:10 Last verified on 04-05-2026
Answer: Antecedent
Explanation In the context of a ratio written as "a:b," the term 'a' is called the antecedent or the first term of the ratio, while 'b' is the consequent or second term. Antecedent : The first term or number in a ratio. Consequent : The second term or number in a ratio. For example, in the ratio 5:2, the antecedent is 5 , and the consequent is 2.
Answer: 100
Explanation To find the amount of solution A and B: Let the amount of solution A be 60 liters. The ratio of A to B is 3:5. Therefore, if A is 60 liters, then B is 5/3 × 60 =100 liters. So, the solutions are 60 liters of A and 100 liters of B.
