Bihar Police Constable Model Paper 5

Given:
It is given that A = LCM of (7xyz,5x2y2‌and‌3‌z3) and B = HCF of (xy, 3yz and -2 yzx)
Concept Used:
Basic concept of HCF and LCM
Calculation:
A = LCM of (7xyz,5x2y2‌and‌3‌z3)
∴ LCM of (7xyz,5x2y2‌and‌3‌z3) = 105 x2y2z3
Now, B = HCF of (xy, 3yz and -2 yzx)
∴ HCF of (xy, 3yz and -2 yzx) = y
Now, the value of A/B
∴ A/B = 105 x2y2z3∕y = 105 x2yz3
Hence, option (1) is correct
