165 $ 11 # 15 & 4 @ 6

• A. 227
• B. 352
• C. 355
• D. 157

Answer 1

Answer:

A. 227

Solution:

Given equation: 165 $ 11 # 15 & 4 @ 6

Symbol	@	$	&	#
Meaning	+	÷	-	×

After replacing the symbols by their meaning, we get:

165 ÷ 11 × 15 - 4 + 6

= 15 × 15 - 4 + 6

= 225 - 4 + 6

= 231 - 4

= 227

Hence, '227' is the correct answer.
