Solution
Ans.1 –a
Hints:
Amount=P(1+R1/100)(1 + R2/100)(1 + R3/100)
Here A=5623.8, R1=3%, R2=5%, R3=4%
Ans.2 – a
Hints:
P=x[(100/(100+R)) + (100/(100 + R))2 + (100/(100+R))3]
Here R=30%, x=973360, Total no of instalments=n.
Ans.3 – c
Hints: CI=SI(1 + R/200)
Here R=10%, SI=400
Ans.4 –b
Hints:
Amount=P(1+R/400)4n
Here P=16000, R= 40%, n=9 months=3/4 yr.
Ans.5 – d
Hints:
SI=(P x R x T)/100
Here. P=1600, SI=1680-1600, T=1yr.
Ans.6 – a
Hints:
Sum due(A)=(SI x TD)/(SI-TD)
Here SI=120, TD=78
Ans.7 – d
Hints: BG=A(R x T)2 / 100(10 +R + T)
Here A=27600, R=5%, T= 3yr.
Ans.8 – c
Hints: Required Sum (A) = (BD x TD)/ (BD-TD)
Ans.9 – a).
Amit share: Bubai Share = 3:1
Amit’s share=(3 x 48000)/4=36000
