Question

Prepare atleast 5 representations using digits from 1 to 10 and ÷, +, -, *, ( ),{ }, [ ] such a way that the result is 100. (Use the digits only once in one representation.)

Answer 1

prepare atleast 5 representations using digits from 1 to 10 and ÷ ,+, - , × , (), {} , [ ] such a way that the result is 100. also we have to use the digits only once in one representation.

there are so many solutions. one of them is :
10 × 9 + 2(8) - 6
now use BODMAS to solve it
= 10 × 9 + 16 - 6
= 90 + 16 - 6
= 106 - 6
= 100.

hence, one solution is ' 10 × 9 + 2(8) - 6 '
