The Correct Option is C
Approach Solution - 1
Using Alligation Rule, the ratio of cost prices of desktop and laptop will be
i.e., \(2: 3\)
∴ The cost of desktop \(=\frac{2}{5}×50000 \)
\(=20,000\)

Approach Solution -2
Let the price of desktop be \(x\) and the price of laptop be \(y\).
\(x+y = 50,000\) \(…….. (1)\)
\(12x+0.9y = 50,000 \times 1.02\)
\(12x+0.9y = 51,000\) \(……… (2)\)
From eq \((1)\) and eq \((2)\)
\(x = 20,000\)
So, the correct option is (C): 20,000.

- There are 240 students in an engineering college. Each student opted for exactly one of three specialisations among Computer Science, Mechanical and Electronics. The total number of students who opted for Computer Science and Electronics is equal to the number of students who opted for Mechanical. 42-5% students who opted for Mechanical are girls. The number of girls who opted for Computer Science is one-third the number of boys who opted for Mechanical. The difference between the number of boys who opted for Electronics and the number of girls who opted for Computer Science is equal to the difference between the number of boys who opted for Computer Science and the number of girls who opted for Electronics. The number of girls who opted for Electronics is 28.

Resultantly, vehicles have been developed that run on diesel, petrol and even on electricity, which is a remarkable innovative development. During a survey about the percentage wise distribution of cars in four different states, the information regarding ratio between the diesel engine cars, petrol engine cars and electric cars was collected. Total number of cars for which data was collected was 8000. Of these, State 1 had 15% of the total cars in the ratio of 3:4:1 (diesel, petrol and electric); State 2 had 20% of the total cars in the ratio of 5:3:2 (diesel, petrol and electric); State 3 had 30% of the total cars in the ratio of 4:5:3 (diesel, petrol and electric), and; State 4 had 35% of the total cars in the ratio of 7:5:2 (diesel, petrol and electric).
Based on the above information, answer the following questions.
