Let the price of one orange be Rs. x.
Then, the price of other orange = Rs. (x + 60% of x) = Rs. x + 3/5x = Rs. 8x/5
So, x + 8x/5 = 26

Therefore either $10 checks = 3 and $50 checks = 4 OR $10 checks = 4 and $50 checks = 3
using this information 1st option gives us the maximum cashed value therefore if we negate this value from total value we will get minimum value o... |

] | A | There are four digits which when squared give the same units digits: 0, 1, 5, 6
0^2 = 0
1^2 = 1
5^2 = 25
6^2 = 36
So a and b must take 2 of these values. They are positive integers so 0 is not possible.
If one of the digits is 1, when the other is multiplied by 1, you will get the same digit. 1*5 = 5
So 1 is out of the... |
