Answer:
GIVEN:-
A typist can type 1080 words in 12 minutes, how many words can she type in 15 minutes at the same speed?
Answer in algebra.
TO FIND:-
No.of words typed in 15mind
SOLUTION:-
1080/12x=15
x=15×1080/12
x=15×90
x=1350
:.The typist can type 1350 words in 15 mins.
EXPLANATION:-
Hey mate!Look below to understand how we got 1350 as answer.
- First of all in the question there is written that the answer must have to be found by algebraic expression.
- So for that we first needed to clear the concept of the question
- In question it's given that 1080 words in 12 mins so how many can be found in 15 mins.
- So for that as we know we cannot directly find it and the no.of words in 12 mins must have also not been found directly
- First we found how much can be type in 1 min.
- So for that we need to divide the terms.
- So we put the equation as 1080/12x so that once the fraction goes to R.H.S. it's sign gets changed and then on simplifying we get 15×90 at last
- We got 90 as 1080 when her divided by 12 gives 90 as quotient.
hope it helped!
