2. Shiela had saved 3,000 in an account that offered r% simple interest per annum in 20 March 2015. If the interest on 6 June 2015 was 50, find the value
of r using Banker's Rule. (7.69%)
3.
Kevin invested 4,000 in an investment scheme on 18th October 2016. The
investment offered a simple interest rate of 5% per annum. By using approximate
time and exact simple interest, find the total interest received on 20th December
2016. (RM33.88)​

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.
