A owes B, Rs. 1120 payable 2 years hence and B owes A, Rs. 1081.50 payable 6 months hence. If they decide to settle their accounts forthwith by payment of ready money and the rate of interest be 6% per annum, then who should pay and how much.

OPtion

1) A, Rs.50
2) A, Rs.70
3) B, Rs.80
4) B, Rs.70
5) A, Rs.60
6) B, Rs.100
7) B, Rs.50
8) A, Rs.90
9) B, Rs.25
10)None of these

Solution

P.W. of Rs. 1120 due 2 years hence at 6%
= Rs. [100*1120 / 100+(6*2)] = Rs.1000
P.W. of Rs. 1081.50 due 6 month hence at 6%
= Rs. [100*1081.50 / 100+(6/2)]
= Rs. [100*1081.50 / 103]
= Rs. 1050
So A owes B, Rs. 1000 cash and B owes a Rs. 1050 cash.
therefore
B must pay Rs.50 to A.

Option 7) B, Rs.50

ganesh babu   10 years AGO

A owes B
Amount-p=npr/100 , 1120-p=2p6/100 (n=2, r=6)
1120=3p/25+p, p=1000
B owes A
Amount-p=npr/100, 1081.50-P=(1/2)p6/100 (n =1/2, r=6)
1081.5=3p/100+P, P=1050

={(100*1081.50)/(100+(6/2))}
={(100*1081.50)/103}
= rs 1050

so a owes b rs 1000 and B owes a rs 1050

DIPAK TIWARI   10 years AGO

Let A owes B X₹
Hence,(1120-X)=(X*6*2)/100
=>X=1000₹
Again let B owes A Y₹
Hence, (1081.50-Y)=(Y*1/2 *6)/100
=>Y=1050₹
Hence B will give 50₹ to A

PAWAN KUMAR   10 years AGO

Let the amount to be paid to B by A be Rs. x and the amount to be paid to A by B be Rs. y.

Now, A's debt after 2 years = x + (x*6*2/100) = 1120
=> x= Rs. 1000
Also, B's debt after 6 months= y + (y*6*1/2*100) = 1081.50
=> y= Rs. 1050
Since y>x so, B will pay Rs. 50 to A .

Devendra Marghade   10 years AGO

If today's A's amount payable to B =x, then
x+ (x*2*6/100)=1120 , x=1000
Similarly,if today's B's amount payable to A= y ,then
y+(y*(1/2)*6/100)= 1081.5, y=1050
So B should pay 1050-1000= 50 Rs. to A

=Rs.[(1081.50*100)/(100+(6*0.5))] =Rs.(1081.50*100)/(103) =Rs.1050
