Answer: Option B
Explanation:
The word ‘OPTICAL’ contains 7 different letters.
When the vowels OIA are always together, they can be supposed to form one letter.
Then, we have to arrange the letters PTCL (OIA).
Now, 5 letters can be arranged in 5! = 120 ways.
The vowels (OIA) can be arranged among themselves in 3! = 6 ways.
Required number of ways = (120 x 6) = 720.

Answer: Option A
Explanation:
| S.P. = 102% of Rs. 600 = | 102 | x 600 | = Rs. 612. | ||
| 100 |
Now, P.W. = Rs. 612 and sum = Rs. 688.50.
T.D. = Rs. (688.50 – 612) = Rs. 76.50.
Thus, S.I. on Rs. 612 for 9 months is Rs. 76.50.
| Rate = | 100 x 76.50 | % | = 16% | |

Answer: Option C
Explanation:
| Let 40% of A = | 2 | B |
| 3 |
| Then, | 40A | = | 2B |
| 100 | 3 |
| 2A | = | 2B | |
| 5 | 3 |
| A | = | 2 | x | 5 | = | 5 | |||
| B | 3 | 2 | 3 |
A : B = 5 : 3.

Answer: Option B
Explanation:
Let C.P. of each article be Re. 1 C.P. of x articles = Rs. x.
S.P. of x articles = Rs. 20.
Profit = Rs. (20 – x).
| 20 – x | x 100 = 25 | |||
| x |
2000 – 100x = 25x
125x = 2000
x = 16.
