Here, total number of days they worked = 72 days Let, the wife worked for x days The husband worked for (72 - x) days According to the question

640x+(72-x)560 = 43,520 ⇒ 640x+40,320-560x = 43,520 ⇒ 80x = 43,520-40,320 ∴x= 320080=40 So, the wife worked for 40 days and the husband worked for (72-40)= 32 days.

A working couple earned a total of Tk. 43,520. The wife earned Tk. 640 per day, the husband earned Tk. 560 per day. If the total number of days worked by both was 72, formulate system of equation and solve the system to find the number of days worked by each. (Equation (সমীকরণ))
