Explanation

P1 = Rs.800

P2 = Rs.400

Time = 2 years

Difference in S.I. = Rs.40

Formula used:

S.I. = (PRT)/100

Calculation:

(P1RT)/100 – (P2RT)/100 = 40

⇒ RT(800 – 400) = 4000

⇒ R = 4000/800

⇒ R = 5%

∴ The rate of simple interest is 5%.

• P is the third stop
• M is the sixth stop
• The stop O is the stop immediately before Q
• N is the stop immediately before L

Question:

In case N is the fourth stop, which among the following must be the stop immediately before P?

A) O

B) Q

C) N

D) L

E) M

Question:

In case L is the second Stop, which among the following must be the stop immediately before M?

A) N

B) L

C) P

D) O

E) Q

Explanation

Let two angles be x and 2x

Given that, angles are supplementary

∴x+2x=180o

 ⇒3x=180

⇒x= 3

180o

 ⇒x=60 o

 Therefore, bigger angle is 2x=120∘

((S.P - C.P)/C.P)*100 will give you the answer.

=((500–450)/450)*100

=(50/450)*100

=(1/9)*100
