Explanation

Let's break it down step by step:

Let the principal amount be P.

According to the problem, the amount becomes 3 times itself in 20 years, so the interest earned is 2P (since 3P = P + 2P).

The simple interest formula is: Interest = (Principal × Rate × Time)/100

We know that Interest = 2P and Time = 20 years. Let's denote the rate as R.

So, 2P = (P × R × 20)/100

Simplifying, we get: R = 10%

Now, let's find the time it takes for the amount to become double (i.e., interest = P):

P = (P × 10 × Time)/100

Time = 10 years

Explanation

Given:

Capacity = 50000 litres = 50 cubic meters (since 1 cubic meter = 1000 litres)

Length (l) = 2.5 m

Depth (h) = 10 m

Let's use the formula for the volume of a cuboid:

Volume = length × breadth × height

50 = 2.5 × breadth × 10

Now, solve for breadth (b):

50 = 25b

b = 50/25

b = 2 m

To find the value of 39/26:

39/26 = 1.5

= 3/2

Explanation

Given |n - 2| = 10:

We have two cases:

1. n - 2 = 10 => n = 12

2. n - 2 = -10 => n = -8

The sum of the two possible values of n:

12 + (-8) = 4
