Answer: 1:5
Explanation 1 hour = 60 minutes Ratio = 60 minutes : 300 minutes = 1 : 5
Answer: 8
Explanation To solve for x, we can set up a proportion based on the given ratio: 2/3 = x/12 We can then cross-multiply: 2 × 12 = 3 × x 24 = 3x Next, we can divide both sides by 3: x = 24 ÷ 3 x = 8 So, the value of x is 8 .
Answer: 35 days
Explanation Total work = 10 × 14 = 140 person-days Days needed by 4 persons = 140 ÷ 4 = 35 days. Last verified on 01-02-2026
Answer: 8:15:30
Explanation Step 1: Understand the meaning We are given two ratios and asked to find a common multiple — that is, a set of values for M, N, and O that fits both ratios proportionally . Given Ratios: M : N : O = 2 : 3 : 5 M : N : O = 4 : 5 : 6 We want to find a new ratio X : Y : Z that is proportional to both these given ratios. Step 2: Check Option B: 8:15:30 Try simplifying 8:15:30 : Divide all terms by 1 (GCD is 1, so already simplified): Still 8:15:30 Now check if it fits the first ratio (2:3:5): 8 ÷ 2 = 4 15 ÷ 3 = 5 30 ÷ 5 = 6 So 8:15:30 = 2×4: 3×5: 5×6 = 2:3:5 scaled up by different amounts? No — wait! Those aren’t consistent scalings. Instead, let’s try another way: Divide 8:15:30 by 4 : 8 ÷ 4 = 2 15 ÷ 5 = 3 30 ÷ 6 = 5 So 8:15:30 → 2:3:5 (matches first ratio) Now divide 8:15:30 by 2 : 8 ÷ 2 = 4 15 ÷ 3 = 5 30 ÷ 5 = 6 So 8:15:30 → 4:5:6 (matches second ratio) 8:15:30 is a common multiple of both 2:3:5 and 4:5:6
Answer: $900,000
Explanation Given: Original price of car = $800,000 Duty increases price in the ratio 9:8 (after:before) Step 1: Understand the ratio The ratio 9:8 means: New Price : Original Price = 9 : 8 So the new price P new P_{text{new}} P new is: P new = 9 /8 × Original Price Step 2: Substitute the values P new = 9/8 × 800 , 000 P new = 9 × 100 , 00 0 = 900 , 000
Answer: 176
Explanation Look at the first pair: 12 → 68 . A common trick: multiply by something and add/subtract. Check: 12 × 6 − 4 = 72 − 4 = 68 Works. Apply the same rule to 30 : 30 times 6 - 4 = 180 - 4 = 176 30 × 6 − 4 = 180 − 4 = 176 30 × 6 − 4 = 180 − 4 = 176
Answer: 48
Explanation Total ratio parts = 7 + 6 = 13 Men ratio = 6 Total employees = 104 Number of men = (6/13) × 104 = 6 × 8 = 48 Last verified on 18-03-2026
Answer: 1000
Explanation Let's break it down: Total amount = Rs. 2400 Nida's share = Rs. 600 Remaining amount = Rs. 2400 - Rs. 600 = Rs. 1800 Nadia and Amara share the remaining amount in the ratio 4:5. Let's divide Rs. 1800 in the ratio 4:5: Total parts = 4 + 5 = 9 Amara's share = (5/9) × Rs. 1800 = Rs. 1000
Answer: 1:4
Explanation 2 days = 48 hours Ratio = 12 hours : 48 hours = 1 : 4
Answer: Rs. 120000
Explanation current ratio = current assets (C.A)/ Current Liabilities (C.L) = 2/1 s, CA = 2 CL Now working capital = current assets (CA) minus Current Liabilities (C.L) = Rs 60000 So, C.A - C.L = 60000 2 C.L - CL = 60000 C.L = Rs. 60000 Now C.A = 2 x 60000 C.A = Rs. 120000 ND5 -09-2023ma
