A. 20
B. 30
C. 40
D. 50
Let the three parts be A, B, C.
Then, A : B = 2 : 3 and B : C = 5 : 8 = (5 x (3/5)) : (8 x (3/5)) = 3 : 24/5
=> A : B : C = 2 : 3 : 24/5 = 10 : 15 : 24
=> B = 98 x (15/49) = 30
If Rs. 782 be divided into three parts, proportional to 1/2 : 2/3 : 3/4 then the first part is:
The salaries A, B, C are in the ratio 2 : 3 : 5. If the increments of 15%, 10% and 20% are allowed respectively in their salaries, then what will be new ratio of their salaries?
If 40% of a number is equal to two-third of another number, what is the ratio of first number to the second number?
The fourth proportional to 5, 8, 15 is:
Two number are in the ratio 3 : 5. If 9 is subtracted from each, the new numbers are in the ratio 12 : 23. The smaller number is:
In a bag, there are coins of 25 p, 10 p and 5 p in the ratio of 1 : 2 : 3. If there is Rs. 30 in all, how many 5 p coins are there?
