Let the monthly salary of Rishi = Rs. 100 X
Amount spent on Rent = 40 X
Remaining amount = 60 X
Amount spent on grocery = 60X * 1/3 = 20X
Remaining amount = 40 X
Let the amount invested in schemes A, B and C be 2p, 3p and 5p respectively,
According to question,
5p - 3p = 4000
2p = 4000
p = 2000
also, 2p + 3p + 5p = 40X
10 * 2000 = 40 X
20000 = 40X
X = 500
Monthly salary = Rs. 50000
Quantity I : salary of Rishi - amount invested in scheme C
=> 50000 - 10000 = Rs. 40000
Quantity II : Rs. 60000
Quantity I < Quantity II
