Question

Select the number from the given options that can replace the question mark (?) below:
If 243 (222) 317, then 548 (?) 621

A.

211

B.

209

C.

210

D.

219

Correct option is D


Pattern:
· Subtract the first number from the last number, and multiply the result by 3 to the middle number:
· For 243 (222) 317: 317 - 243 = 74.
· 74 × 3 = 222
· Apply the same logic for 548 (?) 621: 621 - 548 = 73.
· 73 × 3 = 219.
Final Answer: (d) 219
