Let a, b, c, d be positive integers such that a + b + c + d = 2023. If a : b = 2 : 5 and c: d = 5 : 2, then the maximum possible value of a + c is
Answer: 1442
Text Explanation :
Given, a : b = 2 : 5 and c: d = 5 : 2
⇒ a = 2x, b = 5x, c = 5y and d = 2y
Also, a + b + c + d = 2023
⇒ 2x + 5x + 5y + 2y = 2023
⇒ 7x + 7y = 2023
⇒ x + y = 289
Now, we need to maximise a + c = 2x + 5y = 2(x + y) + 3y = 2 × 289 + 3y.
This can be maximised by maximising y (higher coefficient).
Since x & y have to be natural numbers, least value of x has to be 1, hence maximum value of y will be 288.
⇒ Maximum value of a + c = 2 × 1 + 5 × 288 = 2 + 1440 = 1442
Hence, 1442.

If , which of the following is always true?
- (a)
a = c
- (b)
a = c, and b = d
- (c)
a = c, or a + b + c + d = 0
- (d)
a + b + c + d = 0

Ashok started a business with a certain investment. After few months, Bharat joined him investing half amount of Ashok's initial investment. At the end of the first year, the total profit was divided between them in ratio 3:1 . Bharat joined Ashok after
- (a)
2 months
- (b)
3 months
- (c)
4 months
- (d)
6 months
Answer: Option C
Text Explanation :
Let Ashok's investment be Rs. 2x, hence Bharat's investment is Rs. x.
Ashok invested for 12 months whereas Bharat invested for say m months.
⇒ =
⇒ =
⇒ 3m = 24
⇒ m = 8
∴ If Bharat invested for 8 months it means he invested after 12 - 8 = 4 months of Ashok.
Hence, option (c).
