The number of oranges in three basket are in the ratio 3 : 4 : 5. In which ratio the no. of oranges in first two basket must be increased so that the new ratio becomes 5 : 4 : 3 ?	Choose the correct option
A) 3:4  B) 2:3  C) 1:3  D) 2:1  E) None of these
Solution: Let,   B1 : B2 : B3 = 3x : 4x : 5x   Again,   B1 : B2 : B3 = 5y : 4y : 3y   Number of oranges remain constant in third basket as increase in oranges takes place only in first two baskets.   Hence, 5x = 3y   and,   3x : 4x : 5x   → 9y /5 : 12y /5 : 15y /5 = 9y : 12y : 15y   And,   5y : 4y : 3y → 25y : 20y : 15y   Therefore, Increment in first basket = 16.   Increment in second basket = 8.   Thus, Required ratio = 16 /8=
