   Expression   =	1	+		999	+	692		× 99
   	7					693

   
   

   Correct Option: B

   Expression   =	1	+		999	+	692		× 99
   	7					693

   
   

   =	1	+ 999 × 99 +	692	× 99
   	7		693

   
   

   =	1	+ (1000 − 1) 99 +	692
   	7		7

   
   

   =	1	+	692	+ 99000 − 99
   	7		7

   
   

   =	693	+ 99000 − 99
   	7

   
   Required answer = 99 + 99000 – 99 = 99000

   Expression = 3²⁵ + 3²⁶ + 3²⁷ + 3²⁸
   = 3²⁵ (1 + 3 + 3² + 3³)
   

   Correct Option: D

   Expression = 3²⁵ + 3²⁶ + 3²⁷ + 3²⁸
   = 3²⁵ (1 + 3 + 3² + 3³)
   = 3²⁵ (1 + 3 + 9 + 27)
   = 3²⁵ × 40, which is clearly divisible by 30.
   Hence the given expression is divisible by 30.
