Answer 1

Answer:

rs. 1007.32

Step-by-step explanation:

let the cost of meal be x

cost of meal after discount = x-20% = 0.80x

service charge and gst will be applied on the discounted price.so

0.80x + (0.80x x 5%) +(0.80x x 18%)= 991.20

0.80x + 0.04x + 0.144x = 991.20

0.984x =991.20

x = 1007.32

(~= 1000)

Answer 2

Answer:

The actual answer is ₹1,007.31707.

but some books might show ₹1000 which is an approximate value.

Step-by-step explanation:

1. let the cost of meal be 'x'

2. Cost of meal after discount (x – 20)%

= 0.80x

3. Service charge and GST is always applied on the Discounted Price.

∴ 0.80x + (0.80x × 5%) + (0.80x × 18)= 991.20

=>0.80x + 0.04x + 0.144x = 991.20

=>0.984x = 991.20

=>x = 1007.32
