The average of five number is 60 and the four numbers are 58,72,43 and 48. Find the fifth number.

${\huge{ \underline{ \blue{ \mathcal{Answer:—}}}}}$

Let the Fifth no. be x

we know that the average of n no. is :-

$average = \frac{x1 + x₂ +....xn}{n}$

where x₁ , x₂ ,etc are necessarily not in any pattern.

ATQ

60 =$\frac{58 + 72 + 43 + 48 + x}{5}$

300=$221 + x$

x= $300 - 221 = 79 \: ans$

Fifth no. is 79

Hope it Helps

Answer 2

Answer:

Let the fifth number be =x

Average =60

Average = (58+72+43+48+x) ÷5

60 = (221+x )÷5

60×5 = 221+x

300 = 221+x

300-221 = x

79 = x

x= 79

fifth number is 79
