## If the interest on Rs. 800 in 2 years is more than the interest on Rs. 400 by Rs. 40 in 2 years, find the rate of simple interest.

Let the rate of simple interest be x%. Then, interest on Rs. 800 in 2 years = (800×2)/100 = 16x Interest on Rs. 400 in 2 years = (400×2)/100 = 8x Given, the interest on Rs. 800 in 2 years is more than the interest on Rs. 400 by Rs. 40 in 2 years. So, …

## If m : n = 3 : 2, then (4m + 5n) : (4m – 5n) is equal to :

We can simplify the expression (4m + 5n) : (4m – 5n) by substituting the given ratio m:n = 3:2. Let’s first find the values of 4m and 5n separately: 4m = 4 × (3/5)n (since m:n = 3:2, we can substitute m = (3/5)n) 4m = 12/5n 5n = 5 × (2/5)n (substituting n …

## If the area of a circle is 38.5 m2, then its circumference will be

Using the formula for the area of a circle: A = πr^2 we have: 38.5 = πr^2 Solving for r, we get: r^2 = 38.5/π r^2 ≈ 12.25 r ≈ √12.25 r ≈ 3.5 So the radius of the circle is approximately 3.5 meters. Using the formula for the circumference of a circle: C = …
