QUESTION:-
the sum of three consecutive multiples of 11 is 363.find these multiple.
EXPLANATION:-
Since the numbers are consecutive .So let the numbers be:-
x,x+1,x+2
Multiplying them by 11 we get:-
11x ,11x+11 ,11x+22
Their sum is 363 (given)
11x+133x+33=363
33x=363−33
33x=3301x+11+11x+22
x=330/33
x=10
So .
First multiple =11x=11×10=110
Second multiple =11x+11=110+11=121
Third multiple =11x+22=110+22=132
Answer :-
The multiples of 11 are 110, 121 and 132.
Step-by-step Explanation
To Find :-
- The multiples.
★ Solution :-
Given that,
- The sum of three consecutive multiples of 11 is 363.
Assumption
Let us assume the three multiples as (x), (x + 1) and (x + 2).
According the question,
→ 11(x) = 11x
→ 11(x + 1) = 11x + 11
→ 11(x + 2) = 11x + 22
Therefore,
- 11x + (11x + 11) + (11x + 22) = 363
On solving,
→ 11x + (11x + 11) + (11x + 22) = 363
→ 11x + 11x + 11 + 11x + 22 = 363
→ 11x + 11x + 11x + 11 + 22 = 363
→ 33x + 33 = 363
→ 33x = 363 - 33
→ 33x = 330
→ x = 10
After solving, We got.
The value of x as 10.
______________________
Now, The multiples are :-
- 11x = 11*10 = 110
- (11x + 11) = 11*10 + 11 = 121
- (11x + 22) = 11*10 + 22 = 132.
Hence, The multiples are 110, 121 and 132.
