Question

The average income of sunday and monday of a man is rs 75 if his income on Tuesday is also included the average income will be rs 80 find his income on tuesday

Answer 1

Answer:

90

Step-by-step explanation:

Let,

Income on Sunday = x

Income on Monday = y

Income on Tuesday = z

ATQ,

$\frac{x + y}{2} = 75$

x+y = 150 - (1)

Adding income of Tuesday ,

$\frac{x + y + z}{3 } = 80$

x+y+z = 240

z= 240 - (x+y)

From (1)

z = 240 - 150

z= 90

Income on Tuesday = 90
