Q. What is the Percentage of the Selling price of vegatable oil and cost price of salt ?
Detailed Solution for VITEEE PCBE Mock Test - 3 - Question 21

Selling price of Vegetable oil = 200 + 50 + 25 = $275 million
Cost price of salt = Selling price + Loss = 80 + 30 = $110 million
Therefore, required percentage = 275/110 x 110 = 250%

VITEEE PCBE Mock Test - 3 - Question 22
Save

Directions: Study the following information and answer the question that follows.

The table below shows the percentage profit or loss of five different commodities based on the sum of cost price and shipping cost.

Q. What is the difference between the selling price of Wine and that of Vegetable oil?
Detailed Solution for VITEEE PCBE Mock Test - 3 - Question 22

Total cost price of Wine = 600 + 40 = $640 million
Selling price of Wine = 100 + Profit Percent/100 x CP
= 100 + 7/100 x 640 = $684.8 million
Selling price of Vegetable oil = 200 + 50 + 25 = $275 million
Therefore, required difference = 684.8 - 275 = $409.8 million

VITEEE PCBE Mock Test - 3 - Question 23
Save

Directions: Study the following information and answer the question that follows.

The table below shows the percentage profit or loss of five different commodities based on the sum of cost price and shipping cost.

Q. What is the ratio of the loss on Grains to that on Salt?
Detailed Solution for VITEEE PCBE Mock Test - 3 - Question 23

Cost price of Grains = 100/100 - Loss Percent x SP
= 100/100 -5 x 500 = 100/95 x 500 million
Loss on Grains = CP of Grains - SP of Grains = 50000/95 - 500 = 2500/95 million

Loss on Salt = $30 million

Therefore, required ratio = 2500/95 : 30 = 50 : 57

Total material cost = (95 + 80 + 75 + 70 + 45 + 60 + 15 + 12 + 16 + 25 + 18 + 21) = 532
Total labour cost = (2.1 + 25 + 20 + 18) = 65.1
Therefore, total material cost was approximately 8 times the total labour cost.

Anil buys 12 toys and labels each with the same selling price. He sells 8 toys initially at 20% discount on the labeled price. Then he sells the remaining 4 toys at an additional 25% discount on the discounted price. Thus, he gets a total of Rs 2112, and makes a 10% profit. With no discounts, his percentage of profit would have been
Detailed Solution for VITEEE PCBE Mock Test - 3 - Question 25

Let the CP of the each toy be “x”. CP of 12 toys will be “12x”. Now the shopkeeper made a 10% profit on CP. This means that

12x(1.1)= 2112 or x=160 . Hence the CP of each toy is ₹160.

Now let the SP of each toy be “m”. Now he sold 8 toys at 20% discount. This means that 8m(0.8) or 6.4m

He sold 4 toys at an additional 25% discount. 4m(0.8)(0.75)=2.4m  Now 6.4m+2.4m=8.8m=2112 or m=240

Hence CP= 160 and SP=240. Hence profit percentage is 50%.

A person who has a certain amount with him goes to market. He can buy 50 oranges or 40 mangoes. He retains 10% of the amount for taxi fares and buys 20 mangoes and of the balance, he purchases oranges. Number of oranges he can purchase is:
Detailed Solution for VITEEE PCBE Mock Test - 3 - Question 26

The person can buy 50 oranges or 40 mangoes.

Let the price of one orange be Rs. x

Total amount the person has = Rs. 50x

40 mangoes cost 50x, So one mango costs 1.25x

10% of the total amount is retained for taxi fare = 10% of 50x = 5x

20 mangoes bought for 20 x 1.25x = 25x

Money left with the person = 50x – (Taxi fare) – (Mangoes cost)

= 50x – 5x – 25x = 20x

One Orange was for Rs. x, Therefore, 20 oranges can be bought with Rs. 20 x

Thus, the person bought 20 oranges.

A report consists of 20 sheets each of 55 lines and each such line consists of 65 characters. This report is reduced onto sheets each of 65 lines such that each line consists of 70 characters. The percentage reduction in number of sheets is closest to:
Detailed Solution for VITEEE PCBE Mock Test - 3 - Question 27

No. of Characters in one line = 65

No. of characters in one sheet = No. of lines × No. of characters per line = 55 × 65

Total number of characters = No. of sheets × No. of characters in one sheet = 20 × 55 × 65 = 71500

If the report is retyped –

New sheets have 65 lines, with 70 characters per line

No. of characters in one sheet = 65 × 70

Number of pages required,

Hence, 16 pages will be required if report is retyped.

Hence, reduction of (20 – 16) = 4 pages

% reduction is = (4/20) x 100 = 20%
