# On the basis of logical reasoning, find the correct option to replace ‘?’ in the table:

(a) 225

(b) 75

(c) 45

(d) 30

**Answer: (c) 45**

**Explanation:-
**20 x 5 – 5 = 100 – 5

= 95,

30 x 5 – 5 = 150 – 5

= 145,

Same as,

10 x 5 – 5 = 50 – 5

= 45

Then, the value of ? is 45.

Hence, the correct answer is option (c) 45.
