Answer 1

Answer:

21%

Explanation:

Original price of a mango: Rs. 20

Increased Price of a mango: Rs.20 + 20% of Rs.20 = 20 + 20/100 X 20= Rs.24

Original price of an orange: Rs. 10

Increased price of an orange:Rs.10 + 25% of Rs10=10 +25/100 X 10= Rs12.50

Original price of 10 mangoes and 5 oranges: (10 X 20) + (5 X 10)

                                                                          = 200 + 50 = Rs. 250

Total Price of 10 mangoes and 5 oranges after increase in price:

                                                                      : (10 X 24) + (5 X 12.50)

                                                                      = 240 + 62.50= Rs.302.50

Increase in price: Rs.302.50 - Rs. 250= Rs. 52.50

Percentage increase in the price: $\frac{I ncrease In Price}{Original Price} X 100$

                                                         = $\frac{52.50}{250} X 100$ = 21%
