Answer :

Let's solve the question step-by-step:

(i) A building has 35 floors. Each floor has 8 flats. The number of flats in the building is determined by multiplying the number of floors by the number of flats per floor. So, we have:

- Operation: [tex]\(35 \times 8\)[/tex]

Thus, the correct option is (c) [tex]\(35 \times 8\)[/tex].

(ii) The cost of two different types of candies is ₹25 and ₹35, respectively. To find the total cost of the two candies, we need to add the costs together:

- Operation: [tex]\(25 + 35\)[/tex]

Therefore, the correct option is (d) [tex]\(35 + 25\)[/tex].

(iii) A bus has 60 seats and 40 seats are vacant. To find out how many seats are already occupied, we subtract the number of vacant seats from the total number of seats:

- Operation: [tex]\(60 - 40\)[/tex]

So, the correct option is (c) [tex]\(60 - 40\)[/tex].

Therefore, the operations you need to tick (✓) are:

(i) (c) [tex]\(35 \times 8\)[/tex]
(ii) (d) [tex]\(35 + 25\)[/tex]
(iii) (c) [tex]\(60 - 40\)[/tex]
