A person who has a certain amount with him goes to market. He can buy 50 oranges or 40 mangoes. He retains 10% of the amount for taxi fares and buys 20 mangoes and of the balance, he purchases oranges. Number of oranges he can purchase is:
Solution
Correct Answer: Option D
Taxi fare = 10%
বাকি থাকে = 90%
40 mango = 100% টাকা
20 mango = (100 x 20) / 40 = 50% টাকা
20 mango কেনার পর থাকে = (90-50)% = 40%
100% টাকা = 50 orange
40% টাকা = (50 x 40) / 100 = 20 টি
বাকি থাকে = 90%
40 mango = 100% টাকা
20 mango = (100 x 20) / 40 = 50% টাকা
20 mango কেনার পর থাকে = (90-50)% = 40%
100% টাকা = 50 orange
40% টাকা = (50 x 40) / 100 = 20 টি
