The ratio of the amounts with Mr Umar and Mr Gumar is 3 : 4 . If Mr Gumar gives Rs. 5 to Mr Umar, then the ratio of the amounts with Uma and Gumar is 4 : 3 . Mr Umar gives Rs. 5 to Mr Gumar. Find the ratio of the amounts with them.

Mr . A gave his telephone number to Mr . B .Mr . B remembers that the first two digits were 40 and the remaining four digits were two 3s, one 6 and one 8 . He is not certain about the order of the digits . Mr. B dials 403638. The probability that he will get A ' s house is

Prove that: 2sqrt(3) - 4 is an irrational number, using the fact that sqrt(3) is an irrational number.

Mr. A writes an article. The article originally is error free. Each day Mr. B introduces one new error into the article. At the end of the day, Mr. A checks the article and has (2)/(3) chance of catching each individual error still in the article. After 3 days, the probability that the article is error free can be expressed as (p)/(q) where p and q are relatively prime positive integers. Let lambda=q-p , then find the sum of the digits of lambda .
