Answer 2

Answer:

Given that the average of 7 no. is 225

then, the sum of 7 is 225*7 = 1575

now the sum of first 3 no. is 265

then total sum of first 3 no. is 265*3 = 795

Now we can calculate the sum of last 4 no.

= 1575 - 265

= 780

we have 4 no. which total sum is 780

So, Average = 780/4

= 195
