A. Rs. 6400
B. Rs. 6500
C. Rs. 7200
D. Rs. 7500
E. None of these
Answer: Option A
Step-by-step explanation:
Given : Invested Amount Rs 13900 divided in 2 different schemes A and B at SI 14% pa and 11% pa
Total amount of SI earned in 2years = 3058
To Find : Amount invested in Scheme B
Solution:
Let say Amount invested in Scheme B = 100P
Amount invested in Scheme A = 13900 - 100P
= 100(139 - P)
SI = P x R x T /100
invested in Scheme A =100(139 - P)
R = 14%
T = 2
SI = 100(139 - P) * 14 * 2 /100
= (139 - P)28
= 3892 - 28P
invested in Scheme B =100P
R = 11%
T = 2
SI = 100P * 11 * 2 /100
=22P
3892 - 28P + 22P = 3508
=> 3892 - 6P = 3508
=> 6P = 384
=> P = 64
=> 100P = 6400
Amount invested in Scheme B = Rs 6400
