                        View Hint View Answer Discuss in Forum Given , Remainder = 4 
 According to question ,
 Divisor = 3 × Remainder
 ⇒ Divisor = 3 × 4 = 12
 Again, divisor = 4 × quotient
 ⇒ 4 × quotient = 12Correct Option: BGiven , Remainder = 4 
 According to question ,
 Divisor = 3 × Remainder
 ⇒ Divisor = 3 × 4 = 12
 Again, divisor = 4 × quotient
 ⇒ 4 × quotient = 12⇒ Quotient = 12 = 3 4 
 ⇒ Dividend = 3 × 12 + 4 = 40

 According to the question,
 2N2 = 3042Correct Option: ALet the required number of persons be N. 
 According to the question,
 2N2 = 3042⇒ N2 = 3042 = 1521 2 
 ⇒ N = √1521 = 39
 
-  A number when divided by 3 leaves a remainder 1. When the quotient is divided by 2, it leaves a remainder 1. What will be the remainder when the number is divided by 6?
- 
                        View Hint View Answer Discuss in Forum The least number (dividend) x is obtained as follows :  Correct Option: BThe least number (dividend) x is obtained as follows :  
 y = 2 × 1 + 1 = 3
 x = 3 × 3 + 1 = 10
 When we divide 10 by 6, the remainder = 4
-  A number, when divided by 119, leaves a remainder of 19. If it is divided by 17, it will leave a remainder of :
- 
                        View Hint View Answer Discuss in Forum On dividing the given number by 119, let k be the quotient and 19 as remainder. 
 Then, number = 119k + 19Correct Option: DOn dividing the given number by 119, let k be the quotient and 19 as remainder. 
 Then, number = 119k + 19
 number = 17 × 7k + 17 × 1 + 2
 number = 17 (7k + 1) + 2
 Hence, the given number when divided by 17, gives (7k + 1) as quotient and 2 as remainder.
 Hence , required remainder is 2.
-  The product of two numbers is 9375 and the quotient, when the larger one is divided by the smaller, is 15. The sum of the numbers is :
- 
                        View Hint View Answer Discuss in Forum Let the numbers be p and q and p is greater than q. 
 As given,
 The product of two numbers = 9375
 pq = 9375 .......(i)
 Again,p = 15 q 
 Correct Option: CLet the numbers be p and q and p is greater than q. 
 As given,
 The product of two numbers = 9375
 pq = 9375 .......(i)
 Again,p = 15 q 
 ⇒ p = 15q
 ∴ From equation (i),
 15q × q = 9375⇒ q2 = 9375 = 625 15 
 ⇒ q = √625 = 25
 ∴ p = 15y = 15 × 25 = 375
 ∴ p + q = 375 + 25 = 400
 Hence , The sum of the numbers is 400 .
