Answer 1

Time = 7 year

Step-by-step explanation:

GIVEN

Principal = ₹1000

Rate = 18%

Simple Interest = ₹1260

___________________________

TO FIND

Time

___________________________

We know that,

Simple Interest = ( Principal × Rate × Time ) / 100

1260 = ( 1000 × 18 × Time ) / 100

Time = ( 1260 × 100 ) / ( 1000 × 18 )

Time = 126000 / 18000

Time = 7

Time = 7 year

___________________________

Let's check

We know that,

Simple Interest = ( Principal × Rate × Time ) / 100

Simple Interest = ( 1000 × 18 × 7 ) / 100

Simple Interest = 10000 / 100

Simple Interest = 126000 / 100

Simple Interest = 1260

Simple Interest = ₹1260

According to the Formula :-

1260 = 1000 × 18 × T/100

1260 = 180t

1260/180 = t

7 = t

Therefore , Time is 7 years .

Check :

1260 = 1000 × 18 × 7/100

1260 = 180 × 7
