The man's transport cost is Rs 4800
Step-by-step explanation:
- Step 1: Given that the amount the man spent on food = Rs 16800 which is 42% of his salary. Form an equation where his salary is x.
42% of x = 16800
42/100 × x = 16800
42x = 1,680,000
x = 1,680,000/42 = Rs 40,000
∴ Salary is Rs 40,000
- Step 2: Calculate the man's transport cost.
12% of 40000 = 12/100 × 40000 = Rs 4800
