Solution: প্রশ্নে বলা হচ্ছে যে, P ও Q এর দৈনিক আয়ের সমষ্টি 90 টাকা । P এর চেয়ে Q এর 10 টাকা বেশি আয় করে আর Q এর দ্বিগুণ আয় করে R. P ও Q এর গড় আয় কত ? Here, Q = P + 10 & R = 2Q = 2 (P + 10) প্রশ্নমতে, P + Q + R = 90 => P + (P + 10) + 2 (P + 10) = 90 => 4p + 30 = 90 p = 15 Now, Q = P + 10 = 15 + 10 = 25 = 20Related questions
