This is the rule in parallel circuit that the total resistance of parallel circuit is nearly less than from the smallest resistance in parallel circuit so in these answers nearly value is 146.7 and also from formula given above.

Name suggested product over sum means first product the given values and then sum it now results of both are divided prodect over sum example: two values say R1&R2 the resultant product of sum is R= (R1*R2) / (R1+R2).

R{EQ)=R1*R2 /R1+R2 =150*6800/150+6800=146.7

This is law of parallel addition of resistance.

R = r1*r2/r1+r2 = 146.7

Friends,

Parallel resistance R=(R1*R2)/(R1+R2)
where R1, R2 are the two parallel resistors

Hence,
R = (150*6800)/(150+6800) = 146.7.

sum=150+6800
product=150*6800
therefore
product over sum=1020000/6950
=146.7

product=150*6800=1020000
sum=150+6800=6950
product-over-sum=1020000/6950=146.7
