greatest no=20
least no =0
It is repeated twice so sum of 3 nos=20+0+0=20

so avg of remainig 47 no=470/47=10

sum of 50 numbers is 490 and greatest no =20 + least and least no is said to be zero and repeated twice so only 48 numbers are non zeroes and greatest no is 20+0 we are asked to get 47 numbers average so omitting 0,0,20 form 50 numbers then deduction in sum would be 490-20=470 then average of 47 numbers would be 470/47=10 answer will be 10
