If ax = b, by = c and cz = a, then find the value of xyz.

None of these
Please type your answer before submitting.

Take Third Equation that was given: c^z=a
rnSubstitute for the value of \'c\' from the given 2nd equation
rn=> (b^y)^z=a
rn=> b^yz=a ... on simplification
rnagain substituing for the value of \'b\' from first equation
rn=> (a^x)^yz=a
rn=> a^xyz=a ... on simplification
rn=> xyz = 1 ... since bases are equal on both sides, the exponents/powers should be equal
rnWe got our xyz value as 1.

Ravi, Manjit and Avtaar wanted to go out on a 200 km journey. In the beginning, Ravi and Manjit went by scooter at a speed of 50 km/hr while Avtaar walked at a speed of 10 km/hr. After a certain distance, Ravi got off and started walking at 10 km/hr, while Manjit took his scooter back to pick Avtaar and arrived with him at the destination at the same time as Ravi. Find the total number of hours they took to complete the journey.

Please type your answer before submitting.

X/10 = (X+2Y)/50 so Y=2X similarly (2Y+Z)/50 = Z/10 2Z=Y SO 2X=2Z=Y THEREFORE 2X+X+X=200 SO X= 50 TOTAL TIME TAKEN BY MANJIT = ( 2Y+X+Y+Z)/50 SUBSITUTE TO GET ANSWER AS 8
