Question

58. The mean of four numbers a,b,c,d is 100. IF c = 70, then the mean of the remaining numbers is​

Answer 1

Answer:

a+b+c+d÷4 = 100

a+b+c+d=400

a+b+d+70=40000

a+b+d=330

The mean of this 3 is as follows

(a+b+d) ÷ 3 =

(330) ÷ 3

110

Answer 2

Answer:

110

Step-by-step explanation:

mean of 4 nbers is 100

total of four numbers is 100*4 =400

now total of 3 numbers is 400-70= 330

hence mean = 330/3

=110.ans
