Question

If 40% of 60% of 3/5 of a number is 504, what will be the 25%
of 2/5 of that number?
Select one:
O a. 350
O b. 150
O c. 175
O d. 230

​

Answer 1

Answer:

40/100*60/100*3/5*X=504

X=(504*100*100*5)/(50*60*3)

X=3500

Now 3500*25/100*2/5= 350

Answer is 350

Answer 2

Answer:

let the number is x

then,

40/100*60/100*3/5*x=504

=> 40*60*3*x=504*100*100*5

=> x=504*100*100*5/40*60*3

=> x=504*5*100/4*6*3

=> x=7*5*100

=> x=3500

so the number is 3500

now ,

25/100*2/5*3500

=25*2*7

=350
