Q:

A sum of money invested for a certain number of years at 8% p.a. simple interest grows to Rs.180. The same sum of money invested for the same number of years at 4% p.a. simple interest grows to Rs.120 only. For how many years was the sum invested?

A) 25years B) 15years
C) 20years D) 22years
 
Answer & Explanation Answer: A) 25years

Explanation:

From the information provided we know that,

Principal + 8% p.a. interest on principal for n years = 180 …….. (1)

Principal + 4% p.a. interest on principal for n years = 120 ……… (2)

Subtracting equation (2) from equation (1), we get

4% p.a. interest on principal for n years = Rs.60.

Now, we can substitute this value in equation (2),

i.e Principal + 60 = 120

= Principal = Rs.60.

We know that SI = , where p is the principal, n the number of years and r the rate percent of  interest.

In equation (2), p = Rs.60, r = 4% p.a. and the simple interest = Rs.60.

Therefore, 60 =(60*n*4)/100

=> n = 100/4 = 25 years.

Q:

A polygon has 44 diagonals, then the number of its sides are ?

A) 13 B) 9
C) 11 D) 7
 
Answer & Explanation Answer: C) 11

Explanation:

Let the number of sides be n. 

The number of diagonals is given by nC2 - n  

Therefore, nC2 - n = 44, n>0 

nC2 - n = 44

n2 - 3n - 88 = 0 

n2 -11n + 8n - 88 = 0  

n(n - 11) + 8(n - 11) = 0 

n = -8 or n = 11.

 

As n>0, n will not be -8. Therefore, n=11.
