Answers
Step-by-step explanation:
Given :-
Fares are increased by 12 whole 1 by 2%
Earlier fare was ¥ 400
To find :-
Present fare
Solution :-
Given that
Earlier fare = ¥ 400
Increased percentage = 12 1/2 %
= [(12×2)+1]/2 %
= (24+1)/2 %
= 25/2 %
Now,
The amount is increased in the fare
= 25/2% of 400
= 25/2 % × 400
= [(25/2)/100]×400
= (25/200)×400
= 25×2
= 50
Increased amount in the fare = ¥ 50
Present fare after increased
= Earlier fare + Increased amount in the fare
= ¥ 400 + ¥ 50
= ¥ 450
Answer :-
The present fare is ¥ 450
Answer:
¥450
Step-by-step explanation:
Given :-
% increase in fare = 12(½)%
Earlier fare = ¥ 400
To Find :-
Present fare
Solution :-
12(½) = 12 × 2 + 1/2
12(½) = 25/2
Now,
Present fare = Old fare + Increase percentage of old fair
Present fare = 400 + 25/2 % of 400
Present fare = 400 + (25/2)/100 × 400
Present fare = 400 + 25/2 × 1/100 × 400
Present fare = 400 + 25/2 × 4
Present fare = 400 + 25 × 2
Present fare = 400 + 50
Present fare = ¥450
