As we have given the %table, R has 50% i.e 20, and T has 90% i.e 45 Now use formula for % decrease i.e change/original 45-20/45*100 25/45*100 =55.56~~56%
@Jalalex6 жыл бұрын
Store R sold 20 TV sets (50% of 40), while store T sold 45 TV sets (90% of 50). Therefore store R sold 25 TV sets fewer than store T. Expressed as a percentage of the number of TV sets sold by store T, 25 is 56% of 45 and so the correct answer is 56%, or option b)
@lraoux6 жыл бұрын
56% (a round-up from 55.55...%) is the correct answer. Note that it asks for how much LESS than T, not how much more than R. 125% would be correct if the question were how much more TV's were sold by store T than store R.
@MrCoolrohitb975 жыл бұрын
Since we have two numbers here, 45 (90% of tv for store T) and 20 (50% of tv for store R) , now since 20 is lower that means R is some percent lower than T so (45-20)/45 = 56% will be the percentage decrease for R with respect to T , while (45-20)/20=125% will be the percentage increase for T with respect to R. Hope that helps :)

@udaymhiremath71455 жыл бұрын
It's a percentage change question, so 18=(40*.45) of R and 45=(50*.90) of T are the numbers to be considered. (45-18/45)*100 = 60% i.e close to option B. ***We consider 45 as denominator because they have asked w.r.t. television sets of T. hope this helps.

Calculation is correct just that i think tv sold by R is 50% rather than 45% from the graph

Formula for % decrease: Original # - New # = “the decrease” (“the decrease” / original #) x 100 = the % decrease

I only looked at the bar graph and wrote down R= 50% and T= 90%. Then I tried to find the difference in percentage of 50 and 90. I did this quickly by adding 10 to each number so the 90 turns into 100 and the 50 turns into 60 making it an easy ~60% . So option B becomes the closest answer. I’m not sure if this is correct though. Where to I find the answer?

At 20:45, i considered everything but made the stupid mistake of 8.39(sales tax) + $119.95x(.8×90)= 8644 or something which i then "approximated" as answer choice A. Ouch!

Why 7% sales tax is taken as 107/100 and not 7/100??
@prahladsaldanha5685 жыл бұрын
I think you can do it in two ways. You wanna know what the cost will be including tax. You can find what seven percent of the cost of the product is to know what the tax is alone and then add the price of the product to it (which is simply one hundred percent of the price of product). You eliminate the step where you add by directly calculating what 107% of the price of product is. Let me know if I'm wrong, though.

The right answer is 56% Solution: # R = 40 * (50/100) = 20 # T = 50 (90/100) = 45 Now, T - R = 45-20 = 25 Let Z = % R < # T 25 = Z/100 (45) Z = 2500/45 = 55.55% = 56%
