DIRECTIONS: For the following questions write your answer would be only in single number. Do not write in word. In a coconut grove, (x + 2) trees yield 60 nuts per year, x trees yield 120 nuts per year and (x - 2) trees yield 180 nuts per year. If the average yield per year per tree be 100, then x = _________ *-correct-answer-description-* \[\frac{(x+2)\times 60+x\times 120+(x-2)\times 180}{x+2+x+x-2}=100\] \[\Rightarrow \]  \[\frac{60x+120+120x+180x-360}{3x}=100\] \[\Rightarrow \] \[360x-240=300x\] \[\Rightarrow \] \[60x=240\] \[\Rightarrow \]\[x=4\] *-question-type-* 6 *-question-instructions-* 0
