Question
Sunita distributed 'y' candies among Arjun, Anita, Aman,
and Akash. The number of candies received by Arjun and Aman are in the ratio 3:5 respectively, and that by Anita and Akash are in the ratio 3:4 respectively. Find the value of 'y' if the number of candies received by Anita is 60% more than Arjun and the number of candies received by Aman is 14 less than Akash.Solution
ATQ, Let the number of candies received by Arjun and Aman be 3x and 5x respectively. Thus, the number of candies received by Anita = 3x × 1.60 = 4.8x Number of candies received by Akash = 4.8x × 4/3 = 6.4x According to the question: 6.4x – 5x = 14 1.4x = 14 x = 10 So, the value of 'y' = 10 × (3 + 5 + 4.8 + 6.4) = 10 × 19.2 = 192
