Question
A total of 840 toffees are shared among four siblings in
the ratio (1/7):(1/8):6:8. How many more toffees did the second highest recipient get than the lowest recipient?Solution
ATQ,
Given Ratio = (1/7):(1/8):6:8.
Multiplying all values by 56 i.e. LCM of 7 and 8,
The ratio becomes = 8:7:336:448
So, number of toffees received by the second highest recipient = 840 × (336/799) = 353
Number of toffees received by the least recipient = 840 × (7/799) = 7
So, required difference = 353 - 7 = 346
