Original food bill (P) = Rs. 400
First discount rate (D1) = 15% or 0.15
Second discount rate (D2) = 35% or 0.35
Formula Used:
Total Discount = D1 × P + D2 × (1 - D1) × P
Calculations:
Total Discount = 0.15 × 400 + 0.35 × (1 - 0.15) × 400
Total Discount = 60 + 0.35 × 0.85 × 400
Total Discount = 60 + 119
Total Discount = Rs. 179
The man received a discount of Rs. 179.
