(A)60 (B) 293 (C) 300 (D) 303 

EXP..(D)

Out of the given option only 303 satisfy the condition.

2. How many numbers less than 1000 are multiples of both of 10 and 13 ?

So answer is 7. 

10 और 13 सह-प्रमुख संख्या है। 10 और 13 के उत्पाद = 10 × 13 = 130 

1,000 ÷ 13 = 7 (भागफल) +90 (शेष) 1,000 ÷ 13 = 7 (भागफल) +90 (शेष)
तो जवाब 7 है। 


3. Mohan gets 4 marks for each correct sum and losses 1 marks for each wrong sum. He attempted 30 sum and obtains 50 marks. The number of sums solved correctly is?
