Answer 1

Answer:

C. 47

Solution:

Given :

38 ÷ 10 × 5 - 7 + 10 × 2 

Concept used:

BODMAS table:

Decoding the information, 

Sign	-	×	÷	+
Means	×	÷	+	-

 

After replacing the signs from left to right and using the BODMAS rule,

⇒ 38 + 10 ÷ 5 × 7 - 10 ÷ 2 

⇒ 38 + 2 × 7 - 5

⇒ 38 + 14 - 5

⇒ 52 - 5

⇒ 47

Hence, the correct answer is '47'.
