NCR Corporation Profit & Loss Problems with Solutions

Answer : A
Explanation
Cost price + profit = Selling Price
Cost price is Rs. 90
Profit is 15% of Cost Price=13.5
Selling Price = CP + Profit
=90+13.5 = 103.5
SP is Rs. 103.5

Answer : D
Explanation
Total CP = 90000 & total SP = 100000
=> Gain = SP/CP = 100000/90000 =1.111 =1.11%

Answer : A
Explanation
Let C.P. = Rs. X. Then
X+X% of X = 56
=>X+XxX/100=56
=>X=Rs.40

Answer : C
Explanation
Let two number be x and y. Then,
X+1/y+1=3/4
=> 4x +4 = 3y+ 3
=> 3y- 4x = 1
x-5/y-5=7/10
=>10x ? 50 = 7 ? 35
=>7y-10x = -15
Multiplying (i) by 5, (ii) by 2 and subtracting, we get
Y=35.
Putting y = 35 in (i), we get 4x =104
=> x=26.

Answer : C
Explanation
C.P = RS. 90, Gain =20%
∴ S.P = (120/100*90) = Rs.108
Let the M.P be Rs. x then, 85% of x = 108.
∴ 85/100*x =108 ⇒x=(108*100/85)
= 2160/17.∴ M.P = 2160/17

Answer : A
Explanation
M.P = Rs. 690 and discount= 10%
∴ S.P = 90% of 690 = Rs. (90/100*690)= 621 Rs.
Now, S.P = Rs. 621 and gain% = 8%
∴ C.P = (100/108*621) = 575 rs.
Now , C.P = Rs. 575 , S.P = 690
∴ Gain%= (115/575*100) % = 20%

Answer : D
Explanation
Let the C.P be Rs. x. Then,
80% of x = 48 ⇒ 80/100 *x =48
⇒ x= (48*100/80) = 60
C.P = Rs. 60 and gain =20%
∴ S.P= Rs. (120/100*60) = Rs. 72

Answer : A
Explanation
Let the C.P be Rupee 1 per m.
(S.P of 33m) - (C.P of 33m) = gain =C.P of 11 m
C.P of 33 m = Rs. 33, S.P of 33m =C.P of 44m =Rs.44
Gain = Rs. (44-33) = Rs 11
∴ Gain % = (11/33*100) %= 100/3%

Answer : C
Explanation
(C.P. of 36 oranges)-(s.p of 36 oranges)= loss=S.P of 4 oranges
⇒C.P of 36 oranges = S.P of 40 oranges.
Let the C.P of each be Re 1.
C.P of 40 oranges = Rs. 40, S.P of 40 oranges =36
Loss % = (4/40*100) % =10%

Answer : B
Explanation
Let the cost of production be rs. x. Then,
X* 110/100 *115/100 *125/100 =1265
⇒ X*11/10* 23/20*5/4= 1265
⇒ 11*23*5*x = 1265*800
⇒ x =1265*800/11*23*5 = 800
∴ cost of the production = Rs. 800
