**Ques:- In what ratio must tea at Rs. 62 per kg be mixed with tea at Rs. 72 per kg so that the mixture must be worth Rs. 64.50 per kg?**

**Recent Answer**: :

The answer is A)

y1 = 62 Rs/kg

y2 = 72 Rs/kg

y = 64.5 Rs/kg

y2 – y1 = 10 Rs/kg

The distance between the y and y1 is

y – y1 = 64.5 – 62 = 2.5

x1 = (y – y1)/(y2 – y1) = 2.5/10 = 0.25

x2 = 1 – x1 = 1 – 0.25 = 0.75

The target price is calculated by the lever method.

x1 * y2 + x2 * y1 = 0.25 * 72 + 0.75 * 62.5 = 64.5

The ratio is of y1 to y2 is

0.75 : 0.25

Divide by both by 0.25

3 : 1

**Ques:- Three 6 faced dice are thrown together. The probability that exactly two dice show the same number on them is -.**

**Recent Answer**: :

Let A, B and C be the three 6-faced dice.

Then, according to the question,

Since two dices has to be equal, that value can be any of the 6 faces, i.e., 6C1 cases.

Now for each case, 2 equal dices can be selected from 3 dices in 3C2 i.e., 3 ways.

And for each of the above, the third dice can have any of the 5 remaining faces

The possible outcomes are P(A)=61,P(B)=61,P(C)=65,P(A)=61,P(B)=65,P(C)=61 and P(A)=65,P(B)=61,P(C)=61

Hence the required probability = 61×61×65×6×3=21690=125

**Ques:- How many numbers greater than 5000 can be formed with four of the digits 3, 4, 5, 6, 7 where no digit can be repeated**

**Recent Answer**: :

When none of the digits are repeated:

The hundred’s place can be filled by any of the digits: 2, 3, 5, 6, 7 or 8 except the one which has already been used at the thousand’s place, so it can be filled in 5 ways.

Similarly tens’ place can be filled in 4 ways: only those 4 numbers which have not been use either at hundred’s or thousand’s place.

Unit’s place can be filled in only 3 ways. So, total number of nos. Possible =4×5×4×3= 240

**Ques:- Rajan got married 8 years ago. His present age is 6/5 times his age at the time of his marriage. Rajan’s sister was 10 years younger to him at the time of his marriage. The age of Rajan’s sister is:**

**Recent Answer**: :

38 years

Let Rajan’s present age be x years. Then, his age at the time of marriage = (x – 8) years.

x = 65(x−8)

⇒5x=6x−48

⇒x=48 years

Rajan’s sister’s age at the time of his marriage = (x – 8) – 10 = (x – 18) = 30 years

∴ Rajan’s sister’s present age = (30 + 8) years = 38 years
