Hence Quantity I > Quantity II
Correct Answer: Rs. 2500
Correct Answer: ? 200
Correct Answer: 11,250
Explanation:
SI = PTR/100
SI = PX100/100
SI = P
So, Amount=P+SI=2P?22500 = 2P?P = 11250
Correct Answer: 6 times
Explanation:
A = P(1 + rt/100)
So, A= 3P (it becomes triples)
3P = P(1 + 8r/100)?r = 25%
Now, when t = 20
?A = P(1 + 25*20/100)
?A = P(1+ 5)?A = 6P
So, it becomes 6 times.
Correct Answer: Rs. 7500
Explanation:
Let the sum invested be x.
? 8x/100 + 12x/100 = 1500
? 20x = 150000
? x = 7500
