Please solve the Q6 and Q7.
Q6. We write down all the digits from 1-9 side by side. Now we put ‘+’ between as many digits as we wish to, so that the sum of numbers become 666.
It is explained below
1 2 3 4 5 6 7 8 9 = 666
Now suppose we put plus signs at following places:
12 + 345 + 67 + 89 = 513
What is the average if the sum is 666?
a. 166.5 b. 111 c. 133.2 d. cannot be determined
Q7. what is the average if the sum is 261?
a. 54 b. 52.2 c. 55 d. None of these
Q-6,
1+2+3+4+567+89=666
so average=111
also, 123+456+78+9=666
so average=166.6
may be third also possible
Q-7,
123+45+6+78+9=261
so average=52.2
