Question

if each sweet cost 21/2 rupees how much do 20 sweets cost if my friend paid one third of the amount and I paid the rest calculate my share of the cost? step by step explanation​

Answer 1

Answer:

Step-by-step explanation:

Cost of 1 sweet = 21/2

Cost of 20 sweets = 20 × 21/2

= 10 × 21

=:Rs 210

Total amount = Rs 210

About paid by friend = 1/3 of total amount

= 1/3 × 210 = 210 / 3 = 70 Rs

Hence amount paid by me = 210 - 70 = 140 ,Rs.

In fraction, I paid 1 - 1/3 = 2/3 of the total amount.

Hope it is clear
