Ratio and Proportion

Total parts = 10 + 15 + 6 = 31. The value of one part is 1581 / 31 = 51. B's share is 15 parts, so 15 * 51 = 765. The other options represent incorrect calculations or shares for A or C.

Let the third number be x. First number = 1.2x = 6x/5, second number = 1.5x = 3x/2. Ratio = (6x/5):(3x/2) = 12:15 = 4:5. Option C is correct.

The ratio is 4:3:5. The lowest part is 3 units, which equals Rs. 12,000. Therefore, 1 unit = 4,000. The total ratio is 4+3+5 = 12 units. Total money = 12 * 4,000 = Rs. 48,000.

Amount of C = 8 * 65,000/26 = 20,000 % amount = 20,000 * 100/65,000 = 30.77%

Ratiof of money between B and C = 6 : 9 So, the money C got is 150% of what B got. Therefore, it is 50% more than B.

Total amount B and D got is = 320. Total amount = 24 * 320/16 = 480

Let the total amount be x.

Then, C's share = 4 * x/14

D's share = 2 * x/14

So, (4 * x/14) - (2 * x/14) = 1000

x = 7000

Now, B's share = 3 * 7000/14 = 1500 Option (4) is correct.

Pradeep's monthly salary = Rs. 3000 Savings = Rs. 750 Ratio = 750 : 3000 or 1 : 4

Required ratio = 20 : 26 or 10 : 13

2000K - LZ = 2000 x 700 - 1400 x 2800 = 1400000 - 3920000 = - 2520000

Daily wages are in the ratio 4 : 5 : 4. Working days of A, B, C = 8, 9 and 12 Wages will be in the ratio 32 : 45 : 48. Share of A = 32/(24 + 45 + 48) × 2000 = Rs. 512

It is Rs. 360. Sum that Anu gets is 2/9 x 540 = Rs. 120 Sum that Charu gets is 4/9 x 540 = Rs. 240 Hence, the combined sum that Anu and Charu get is Rs. 120 + Rs. 240 = Rs. 360 This answer is correct.

2 X + 3 X + 4 X = 36, 9 X = 36, X = 4. Therefore, Sita gets Rs. 4 X = Rs. 16

Share of B = 3/10 * 20000 = 6000 Share of C = 5/10 * 20000 = 10000 Difference between their shares = 10000 - 6000 = 4000

Let A get Rs. 3x, B get Rs. 2x and C get Rs. x. Therefore, (3x + 2x + x) = Rs. 3600 6x = Rs. 3600 x = 600 Therefore, C will get Rs. x = Rs. 600. B will get Rs. 2x = Rs. 1200. A will get Rs. 3x = Rs. 1800.
