Questions on Binary conversions
1. Convert binary number 11111 to decimal?
a. 21 b. 31 c. 41 d. 25
2. Write the binary number 101.11 in decimal?
a. 2.1 b. 3.5 c. 4.1 d. 5.25
3. Determine whether the following statements are true or false.
- 1001_{2} < 5_{10}
- 0111_{2} = 111_{10}
- 0011_{2} > 2_{10}
- 1001_{2} > 1101_{2}
- 1011_{2} = 11_{10}
- 1111_{2} = 15_{10}
- 0000_{2} < 0_{10}
- 1101_{2} > 1010_{2}
1.
31 is the correct answer.
We arrive at the answer by the following process:
2^{4} + 2^{3} + 2^{2} + 2^{1} + 2^{0} = 31 in decimal.
2.
1*2^{2 } = 1*4 = 4.
0*2^{1 } = 0*2 = 0.
1*2^{0 } = 1*1 = 1.
1*2^{-1} = 1*.5 = 0.5
1*2^{-2} = 1*.25 = + 0.25
5.75
3.
Binary | Decimal | Answer | |
a. | 1001_{2} < 5_{10} | 9_{10} < 5_{10} | False |
b. | 0111_{2} = 111_{10} | 7_{10} = 111_{10} | False |
c. | 0011_{2} > 2_{10} | 3_{10} > 2_{10} | True |
d. | 1001_{2} > 1101_{2} | 9_{10} > 13_{10} | False |
e. | 1011_{2} = 11_{10} | 11_{10} = 11_{10} | True |
f. | 1111_{2} = 15_{10} | 15_{10} = 15_{10} | True |
g. | 0000_{2} < 0_{10} | 0_{10} < 0_{10} | False |
h. | 1101_{2} > 1010_{2} | 13_{10} > 10_{10} | True |

The Basic Steps
The basic steps for a date in the years 2000-2099 are as follows:
Example date July 13th, 2004
1.Take the last 2 digits of the year and add a quarter onto itself. (04 + 1 = 5) ignore the decimals.
2.Get the corresponding code for the month. (January = 6, February = 2, March = 2, etc. See month codes for details). July = 5
3.Take the day. (=13)
4.Add the numbers together (5 + 5 + 13 = 23)
5.Take away 7 (or multiples of 7) until a number from 1-7 is left. (23 – 21 =2)
6.This number corresponds to the day of the week. (1 = Monday, 2 = Tuesday, etc.) In this case 2 = Tuesday

All kind of tedious CMAT quant questions are covered in our classes.
