Answer 2

Answer:

Total amount = Rs. 400

amount spent = Rs. 120

Step-by-step explanation:

let x be the total amount

given ,

x - 280 = x * (30/100)

=> x - 280 = (30x/100)

=> 100(x - 280) = 30x

=> 100x - 28000 = 30x

=> 100x - 30x  = 28000

=> 70x  = 28000

=> x  = 28000/70

=> x = 400

=> the Total amount = Rs. 400

amount spent = 30% of Rs.400

                       = 400 * (30/100)

                       = 30*4

                       = Rs. 120
