Answer:
9×9........,.......
Proper question :- The sum of three consecutive multiples of 9 is 81. Which is the least among these three multiples?
Solution :-
Let the three consecutive multiples of 9 be x, x + 9 and x + 18
Their sum is 81
According to the given condition,
x + x + 9 + x + 18 = 81
➾ 3x + 27 = 81
➾ 3x = 81 - 27
➾ 3x = 54
➾ x = 18
∴ Smaller number ➾ x
➾ 18
∴ Second number ➾ x + 9
➾ 18 + 9
➾ 27
∴ Third number ➾ x + 18
➾ 18 + 18
➾ 36
