Let Jackson invested Rs. x at the rate of interest 12% and remaining amount Rs. (20,000 - x) at the rate of 10%.
According to the question,
12% of x + 10% of (20,000 - x) = 2280
0.12x + 0.1(20,000 - x) = 2280
0.12x + 2000 - 0.1x = 2280
0.02x = 280
x = Rs. 14,000
Jackson invested Rs. 14,000 at 12% and (20,000 - 14,000) = Rs. 6000 at 10%.

[tex]\bf{\red{:→}}[/tex] Let the money invested by jackson be Rs.x at a rate of interest 12% and the remaining amount be 20,000-x at the rate of 10%.
[tex]\bf{\bold{\red{As~per~the~question,}}}[/tex]
[tex]\bf{\red{:→}}[/tex] 12% of x + 10% of (20,000-x) = 2280
[tex]\bf{\red{:→}}[/tex] 0.12x + 0.1(20,000-x) = 2280
[tex]\bf{\red{:→}}[/tex] 0.02x = 280
[tex]\bf{\red{:→}}[/tex] x = ₹14,000
[tex]\bf{\red{:→}}[/tex][tex]\bf{\bold{\red{Jackson~invested=Rs.14,000}}}[/tex] at 12%
