Simple interest on a certain sum is 16/25 of the sum. Find the rate percent and time, If both are numerically equal. | [
"Rate = 8% and Time = 8 years.",
"Rate = 7% and Time = 7 years.",
"Rate = 5% and Time = 5 years.",
"Rate = 6% and Time = 6 years."
] | A | Explanation:
Sol: Let sum = X. Then S.I = 16x/25
Let rate = R% and Time = R years.
Therefore, (x * R * R)/100 = 16x/25 or R^2 = 1600/25, R = 40/5 = 8
Therefore, Rate = 8% and Time = 8 years.

A girl scout was selling boxes of cookies. In a month, she sold both boxes of chocolate chip cookies ($1.25 each) and boxes of plain cookies ($0.75 each). Altogether, she sold 1,585 boxes for a combined value of $1,588.25. How many boxes of plain cookies did she sell? | [
"695",
"0",
"233",
"786"

Running at their respective constant rate, machine X takes 2 days longer to produce w widgets than machines Y. AT these rates, if the two machines together produce 5w/4 widgets in 3 days, how many days would it take machine X alone to produce 2w widgets. | [
"6",
"10",
"12",
"4"
] | C | rx*(t+2) = w
ry*(t) = w.
Also, w/(t+2) + w/t = (5w/4)*(1/3)
or 1/t + 1/(t+2) = 5/12 --> (3+2)/12 = 1/4+1/6
Thus, t = 4. Replacing, rx = w/6,
w/6*T = 2w
or T = 12 days.

Age of Raghav who is 30 years old is 3/5 times of Ram and Ram is older than Mohan by 35 years.If vijay's age is just between the age of Ramesh and and Mohan and Ramesh is 21 years old.What is age of vijay? | [
"25",
"17",
"18",
"20"
] | C | Solution:
Raghav's age=3/5 Ram's age
=>30=3/5 Ram's age
=>Ram's age=30/3 * 5=50
Ram's age=Mohan's age +35
=>Mohan's age=Ram's age -35
=>Mohan's age=50-35
=>Mohan's age =15
Vijay's age=(Ramesh's age +Mohan's age)/2
=>Vijay's age=(21+15)/2
=>Vijay's age=18 years.

Length of a rectangular plot is 20 mtr more than its breadth. If the cost of fencin gthe plot at 26.50 per meter is Rs. 5300, what is the length of the plot in mtr? | [
"30 m",
"60 m",
"70 m",
"65 m"
] | B | Let breadth = x metres.
Then, length = (x + 20) metres.
Perimeter = 5300 m = 200 m.
26.50
2[(x + 20) + x] = 200
2x + 20 = 100
2x = 80
x = 40.
Hence, length = x + 20 = 60 m
