206For 1 turn of 54 cogged wheel(say A), there is 5432 turns of the 32 cogged wheel(say B)
Now, A turns 80 times in 3 quarters of a minute
→ A turns 80 times in 45 seconds
→ A turns 8045 times in 1 second
ATQ, we need to find how many times B turns in 45 seconds.
Then, from above, B turns (5432 x 8045 x 45) times in 45 seconds
Hence, B turns 135 times in 45 seconds.
