Question
The combined value of ‘r’ and ‘s’ is 750. If
‘r’ is decreased by 4% and ‘s’ is increased by 16%, they become the same. Find the value of ‘s’.Solution
ATQ,
r + s = 750 ……(i)
ATQ,
0.96 × r = 1.16 × s
Or, r = (1.16 / 0.96) × s
So, r = (29s / 24)
Put the value of ‘r’ in equation (i), we get,
(29s/24) + s = 750
Or, (53s/24) = 750
Or, s = 750 × (24/53)
So, s = 339.62
