The table given below shows the production of rice and the area under rice cultivation of a country for 5 consecutive years Y1, Y2, Y3, Y4 and Y5.
| Year | Rice Production (in 1000 kg) | Area Under Rice Cultivation (in 100 square meter) |
| Y1 | 520 | 130 |
| Y2 | 570 | 190 |
| Y3 | 680 | 150 |
| Y4 | 720 | 180 |
| Y5 | 850 | 170 |
What is the percentage change in the yield per square meter of Y5 as compared to Y1?
Show answer & explanation

| Understanding/Application |
|
Yield per square meter of Y5 = 850/170 = 5 Yield per square meter of Y1 = 520/130 = 4 |
