Question

A man purchased some eggs at 3 for Rs 5 and sold them at 5 for Rs 12 . Thus , he gained Rs 143 in all . How many eggs did he purchase?​

Answer 1

Answer: 195

Step-by-step explanation: Let the total number of eggs be x.

Cost price= total no. × price of one egg

As 3 eggs cost RS. 5 therefore 1 egg costs RS . 5/3 .

Cost price = RS .5x/3

Similarly Sell price= RS. 12x/5

Now it's given that total gain = RS. 143

We know gain= Sell price-cost price

= 12x/5-5x/3= 11x/15

Therefore x= 15×143/11= 195
