Answer:
A. Systematic
Explanation:
it is because he ask each student in that particular class, so that he question them in a systematic way.
Answer:
90(Initial Weight) + <em>W*t = 138 Kg </em>
So the Weight increased per month is 6Kg
Explanation:
The Wrestler started at 90Kg weight
After 8 months, Wrestler had a weight of 138Kg.
The weight gained by the wrestler in '<em>t'</em> months is:
138(Kg) - 90 (Kg) = 48 (Kg)
From above equation we can see that a difference of 48Kg was attained by Wrestler.
Since the question stated that, the weight increased at a constant rate, so we can calculate the weight gained each month over a period of 8 months.
Weight gained per month: 48 (Kg) / 8 (Months) = 6 (Kg) / (Month)
So now we can write the equation in terms of <em>W</em>(Gained per month) and<em> t</em>( t number months)
The equation becomes:
90Kg (Initial Weight) + <em>W.t = 138 Kg </em>
<em>( where 'W' is Weight increased per month and 't' is number of months passed)</em>
