Question: An amount of money was divided among 3 boys in such a way that the first boy was given twice the third boy and the second boy was given equal to third boy. If the average is 400 Taka. How much was the first boy given?

Solution:
ধরি,
তৃতীয় বালক পায় = ক টাকা
∴ প্রথম বালক পায় = ২ক টাকা

প্রশ্নমতে,
(২ক + ক + ক)/৩ = ৪০০
৪ক/৩ = ৪০০
ক = ৩০০ টাকা

∴ প্রথম বালক পায় = ২ × ৩০০ = ৬০০ টাকা।
