Ramesh got 49/4 dozen T-shirts in 12 % discount to printed price and he sold two third of these T-shirts in 19 % profit to printed price, then he sold other T-shirts in printed price. If his overall profit is 3626 rupee then printed price of the T-shirt is
Let the printed price of the T-shirt is x, then according to given condition
1.19 x * 2/3 (147) + x * 1/3 (147) � 0.88 x *(147) = 3626
On solving this equation, we get x= 100
A packet of toffee contains 57 toffees. The cost of packet is 44 rupee but every toffee is sold in 1 rupee separately. Find the percentage profit on selling the toffees one by one relative to sell the packet.
Total no. of numbers formed by using the given digits 3,3,4,5,5,8,9 = (7*6*5*4*3*2*1)/(2*1)*(2*1) = 1260
(Denominator part is due to the repetition of 3 and 5)
Total no. of numbers formed by using the given digits 3,3,4,5,5,8,9 which are greater than 57,26,000 are of two types
Total no. of numbers started with 5 = (2*2*5*4*3*2*1)/ (2*1)*(2*1) = 120
Total no. of numbers started with 8&9 = (2*6*5*4*3*2*1)/ (2*1)*(2*1) = 360
Hence required probability = (120 + 360)/ 1260 = 480/1260 = 8/21
There are two schemes in Vodafone mobiles.
First scheme :1 paise per second,
Second scheme :50 paise per minute,
Following conditions are given -
1) In second scheme, second minute will be started at 0:60 or 1:00,
2) 0 sec. call means to call and cut it abruptly when timer reads 0:00, this is equivalent to a call of 1 sec.
3) In first scheme 0:14 means 15 sec.
The probability that first scheme is more profitable over second in a call ranging from 0:00 (1 sec.) to 3:20 (201 sec.) is ?
The ranges in which first scheme is more profitable over second in a call ranging from 0:00 (1 sec.) to 3:20 (201 sec.) is ?
0-48, 60-98, 120-148, 180-198,
Hence total seconds in which first scheme is more profitable over second are 136.1
Therefore probability that first scheme is more profitable over second in a call ranging
from 0:00 (1 sec.) to 3:20 (201 sec.) is 136/201.
