Answer: Between 194 and 195
Step-by-step explanation: Compatible numbers are numbers in pairs that by mental exercise one can easily add, subtract, multiply, or divide. This is applied usually in estimation to approximate a calculation. Here, you replace actual numbers with compatible numbers (easy to estimate pairs).
Two numbers with close quotients with 1754 on dividing by 9 are by estimation 194 and 195. To check, on multiplying these figures by 9 you get 1746 and 1755 respectively. 1755 is actually very close to the required result, therefore 195 is a better estimate than 194 if we were to pick just one. So 194 and 195 fits perfectly
