The monthly salary of a person was Rs. 160000. He used to spend on three heads--- Personal and family expenses (P), Taxes (T) and Education load (E). The rest were his savings. P was 50% of the income, E was 20% of P, and T was 15% of E. When his salary got raised by 30%, he maintained the percentage level of P, but E became 30% of P and T became 20% of E. The sum of the two savings (in Rs.) is:
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 128160
Salary of a person = 160000.
P = 1/2 × 160000 = 80000.
E = 20% of 80000 = 16000
T = 15% of 16000 = 2400.
Savings = 160000 - 80000 - 16000 - 2400 = 61600
Now his income increased by 30%
New salary = 160000 × 130% = 208000.
New P = 50% of 208000 = 104000.
New E = 30 % of 104000 = 31200
New T = 20% of E = 31200 = 6240.
Savings = 208000 - 104000 - 31200 - 6240 = 66560.
Total savings = 61600 + 66560 = 128160.
