To find the ratio of 12 minutes to 1 hour, we first convert 1 hour into minutes:
1 hour = 60 minutes.
Now, the ratio of 12 minutes to 60 minutes is:
12/ 60= 1/ 5
In given ratio 3 : 4
3 is antecedent
4 is consequent.
To find the interest earned using the simple interest formula, use:
Simple Interest = 𝑃 × 𝑟 × 𝑡
where:
P is the principal amount ($1200),
r is the annual interest rate (5% or 0.05),
t is the time in years (2 years).
Substitute the values into the formula:
Simple Interest=1200×0.05×2
Calculate:
Simple Interest=1200×0.05=60
Simple Interest=60×2=120
A ladder slides 12cm in 3 minutes. it will slide 48cm in 12 minutes
To calculate the interest, you can use the formula:
Interest = Principal × Rate × Time
In this case:
Principal (P) = Rs. 500
Rate (R) = 11% per annum = 0.11
Time (T) = 4 years
Interest = 500 × 0.11 × 4 = Rs. 220
So, Mr. Ali has to pay back the principal amount of Rs. 500 plus the interest of Rs. 220, making a total of Rs. 720.
The correct answer is: Rs. 220
