The sum of four numbers is 126. The ratio of first number to the seco...
Let, the first number and the second number be 4x and 3x respectively
Let, the third number and the fourth number be 3y and 4y respectively
According to the question,
4x+3x+3y+4y=126
7x+7y=126
x+y=18
Also,
4y – 3x = 30
4y – 3(18 – y) = 30
4y – 54 + 3y = 30
7y = 84
y = 12
So, x = 18 – y = 18 – 12 = 6
So, the first number = 6 x 4 = 24
And the third number = 3 x 12 = 36
Therefore, the required average = (24+36)/2=60/2=30
So option (b) is the correct answer.

Study the following information carefully and answer the below questions.Eight persons – Meloditha, Elexa, Zen, Xbaithya, Naincy, Defa, Aadithya, and Yogitha are living in a four floor building marked 1 to 4 from bottom to top respectively. There are two flats on each floor viz.- flat I and flat II from west to east respectively. Each person wears a jersey with different numbers printed on the back.Note:I. If the number of letters in the person’s name is even, then their jersey numbers are obtained by multiplying the total number of letters of their name by either 4 or 5. (E.g.)The total number of letters in the name is 6. Then the person’s jersey number is either ‘24’ or ‘30’.II. If the number of letters in the person’s name is odd, then their jersey numbers are obtained by multiplying the total number of letters of their name by either 3 or 6. (E.g) The total number of letters in the name is 3. Then the person’s jersey number is either ‘9’ or ‘18’.III. If the person’s name starts with a letter which is in the first half of the alphabetical series, then the person lives on an odd numbered floor, else the person lives on an even numbered floor.Naincy lives two floors below the one whose jersey number is a multiple of 10 but both are not living in the same flat. The one whose jersey number is 20 lives two floors above the one whose jersey number is 12 less than Meloditha in the same flat. Meloditha lives immediate southwest of the one whose jersey number is 11 less than the jersey number of Aadithya. Aadithya lives southwest of the one whose jersey number is six more than Zen.What is the sum of the jersey number of the persons living on floor number 3?
