I spent 3/4 of my money and then I spent 1/5 of what was left Everybody keeps saying that it is 11/20 but that is NOT CORRECT

Thank you!

Money spent = 3/4

money left = 1-(3/4) = 1/4

.

.

again 1/5 spent of 1/4 (remaining money) = 1/20

means again money was spent = 1/20

total money spent = 1/4 + 1/20 = 6/20 = 3/10 of total

now, total money left = 1 - (3/10) = 7/10

hence, 7/10 part of total money is left after all expenditure!

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
