A boy buys 18 sharpeners (brown or white) for Rs. 100. For every white sharpener, he pays one rupee more than the brown sharpener. What is the cost of white sharpener & how much did he buy?
A5, 13
B5, 10
C6, 10
DNone of these
Answer: Option C
Explanation:Assume that he bought b, brown sharpeners and w, white sharpeners and the cost of brown sharpener is x and white sharpener is x + 1
So w(x+1) + bx = 100
w + b = 18
b = 18 - w
Substituting in equation 1, we get w(x+1) + (18 -w)x = 100 so w + 18 x = 100
Take option 1: If white sharpners are 13, x = (100 - 13) /18 = 4.833
Option 2, If white sharpeners are 10, x = (100 - 10)/18 = 5 So white sharpeners cost is 6.
Option 3 Satisfies this condition.

A20%
B14.28%
C16.66%
D11.01%
Answer: Option B
Explanation:A:B:C=110*3:110*6:440*3 = 3:6:12 = 1:2:4
share of A = 1/(1+2+4) * 7000 = 1000
% expenditure of A = 1000/7000 *100 = 100/7 = 14.28%

The cost price of two types of tea are Rs. 180 per kg and Rs. 200 per kg respectively. On mixing them in the ratio 5:3, the mixture is sold at Rs. 210 per kg . In the whole transaction, the gain percent is
A10%
B11%
C12%
D13%
Answer: Option C
Explanation:Mixing ratio=5:3
1st type tea=5/8
2nd type of tea=3/8
therefore 1 kg of mixed tea price/kg=>180*(5/8)+200*(3/8)=187.5.
total profit=210-187.5=22.5
therefore % of profit=(22.5/187.5)*100=12%
ratio is 5:3
5x+3x=210
8x=210 => x=1680
1st type tea = 180*5 =900
2nd type tea = 200*3=600
total is =1500
profit=1680-1500 = 180
gain= (180/1500)*100= 12%

A circular tent is cylindrical to a height of 3 meters and conical above it. If its diameter is 105 m and the slant height of conical portion is 53m, calculate the length of the canvas 5 m wide to make the required tent?
A973.5
B3894
C1800
D1947
Answer: Option D
Explanation:Surface area of Tent= surface area of the cylinder + surface area of the cone
=(2*pi*r*h)+ (pi*r*l)
=2*(22/7)*(105/2)*3+(22/7)*(105/2)*53
=9735 sq.m
l*b=9735
b=5m,
l=9735/5 => l=1947m
