For an agricultural experiment, 300 seeds were planted in one plot and 200 were planted in a second plot. If exactly 25 percent of the seeds in the first plot germinated and exactly 35 percent of the seeds in the second plot germinated, what percent of the total number of seeds germinated?

A) 12% B) 26% C) 29% D) 30% E) 60%

From the first plot 0.25*300=75; From the second plot 0.35*200=70;

For an agricultural experiment, 300 seeds were planted in one plot and 200 were planted in a second plot. If exactly 25 percent of the seeds in the first plot germinated and exactly 35 percent of the seeds in the second plot germinated, what percent of the total number of seeds germinated?

A. 12% B. 26% C. 29% D. 30% E. 60%

In the first plot 25% of 300 seeds germinated, so 0.25 x 300 = 75 seeds germinated.

In the second plot, 35% of 200 seeds germinated, so 0.35 x 200 = 70 seeds germinated.

Since 75 + 70 = 145 seeds germinated out of a total of 300 + 200 = 500 seeds, the percent of seeds that germinated is (145/500) x 100%, or 29%.

For first plot germinated seeds = .25 * 300 = 75 For second plot germinated seeds = .35 *200 = 70 Total planted seeds = 500 Total germinated seeds = 145 Percent of the total number of seeds germinated = \(\frac{145}{500}\) * 100 = 29% Correct Answer - C

A) 12% B) 26% C) 29% D) 30% E) 60%

Seeds planted in one plot = 300 Seeds germinated in one plot = 25% of 300 = \(\frac{25}{100}\) x 300 = 75

Seeds planted in second plot = 200 Seeds germinated in second plot = 35% of 200 = \(\frac{35}{100}\) x 200 = 70

Total seeds planted = 300 + 200 = 500 Total number of seeds germinated = 75 + 70 = 145

Percent of the total number of seeds germinated = Total seeds germinated / Total seeds planted x 100 = \(\frac{145}{500}\) x 100 = 29% Answer C...

First plot : 300 seeds Second Plot : 200 seeds

Seeds germinated in 1st plot = .25*300 = 75 Seeds germinated in 2nd plot = .35 * 200 = 70 Total seeds germinated = 145

Total seeds planted = 500 Percentage of seeds germinated = (145/500)*100 = 29%

We are given that 25% of 300, or 0.25 x 300 = 75, seeds germinated in the first plot. We are also given that 35% of 200, or 0.35 x 200 = 70, seeds germinated in the second plot. Thus, a total of 75 + 70 = 145 seeds germinated, or 145/500 = 29/100 = 29% of the seeds germinated.

Answer: C
