## Quant questions

Some doubts.. help me in solving them Q1.Find the sum of the digits in the expanded product 199,999,997 x 200,000,003. a. 129 b. 139 c. 229 d. 239 Q2.What is the angle between the two lines passing through the points (1, 2) (4,2) and (-3, 6) Q3. What is the smallest integer x larger than 1 such that x^2 ends in the same three digits as x does? a. 476 b. 376 c. 276 d. 176

## 3rd question

The answer is 376 as 376^2 = 141376 And I found it by calculating the square of all the numbers but I am sure there must be a better method. If few options are of 5-6 digits then we finding the square might not be the best method
