(A) 179

(B) 279

(C) 379

(D) 479

Ans: B

The required number = \$\${LCM × HCF} / {First number}\$\$ = \$\${5301 × 9} / {171}\$\$ = 279.

Question: 2

The H.C.F. and L.C.M. of two numbers are 44 and 264 respectively. If the first number is divided by 2, the quotient is 44. The other number is

(A) 66

(B) 132

(C) 264

(D) 384

Ans: B

First number = 2 × 44 = 88

Second number = \$\${44 × 264} / {88}\$\$ = 132.
