B covers 28 meters in 7sec. So, B’s time over the course = (7/28)*1000 =250 sec.
Whereas A’s time over the course = 250 -7 = 243 sec.
i.e A’s time over the course is 4min, 3 sec
Paid= 3/5
Remaining = 1 – 3/5 = 2/5
Given conditions:
2/5 x Total amount = 400
⇒ Total amount = 1000
July is 7th month of English Calendar
The odd-numbered months are January, March, May, July, September, and November, being the 1st, 3rd, 5th, 7th, 9th, and 11th,
while the others are even months.
So there are 6 odd months and 6 even months.
To find the solution, first, calculate the total man-days required for the job: 36 men * 18 days = 648 man-days.
Then, divide the total man-days by the new number of men (27) to find the new number of days: 648 man-days / 27 men = 24 days.
So, the correct answer is 24.
To solve this problem, we can use the concept of man-days:
8 people × 60 days = 480 man-days
Since the amount of work remains the same, we can set up an equation for 6 people:
6 people × x days = 480 man-days
To find the number of days, divide 480 by 6:
x = 480 ÷ 6
x = 80 days
Equilateral Triangle Three equal angles, always 60
all sides are of equal length (equilateral), and all angles are right angles.
A triangle that has no equal sides and no equal angles is known as a Scalene Triangle
while
if two sides of a triangle are of equal length, then it is called. Isosceles triangle
Let the number be x
Then,
⇔34x−13x=60
⇔5x12=60
⇔x=(60×125
)⇔x= 144
