Do you know what seems ODD to me? Those numbers which are not divisible by 2.

Inolas

The wonder is not that mathematics describes the world so well but that it describes it at all.

A student purchased a computer system and a colour printer. If he sold the computer system at 10 % loss and the colour printer at 20 % gain, he would not lose anything. But if he sells the computer system at 5 % gain and the colour printer at 15 % loss, he would lose Rs. 800 in the bargain. How much did he pay for the colour printer?

Reply Like? Yes | No

(7 years ago)

Answer: B
Let C and P be the cost price of Computer and Printer respectively.
So CP = C + P, Case I,
SP = 0.9C + 1.2P.
Since he did not lose anything C + P = 0.9C + 1.2P  C = 2P.
Case II, SP = 1.05C + 0.85P
Since there was the loss of Rs. 800
Rs.800 = C + P – 1.05C – 0.85P
 80000 = 15P – 5C
Using equation from Case I, we get P = Rs.16000.

At the beginning of 4th year, 1120 is the principal which amounts to 1200 in one year. So interest for 1 year = Rs. 80
Interest for 4 years = 80*4 = 320
A = P + SI
P = A - SI = 1120-320 = Rs. 800

@Deepanshi: 0.0xyxyxy..= (0xy-0)/990=xy/990 ; since 0.xyxyxy..=3/55 which implies xy=54 now xy can be written as 10x+y=54 as xy is two digit number which yields x=5 and y=4 ans: 20;

x*1.05= y*1.1= z*1.15 => x:y:z= 1/21:1/22:1/23 = 23*22:21*23:22*21 = 506:483:462 also x+y+z=1451 => x=506 y=483 z=462
