The perimeters of two squares are 40 cm and 36 cm. Find the perimeter of a third square whose area is equal to the difference of the areas of the two squares . | [
"28 cm",
"29 cm",
"24 cm",
"17.6 cm"
] | D | Explanation:
We know perimeter of square = 4(side)
So Side of first square = 40/4 = 10 cm
Side of second square = 36/4 = 9 cm
Area of third Square = 10*10 - 9*9
= 19 cm
So side of third square = 4.4 [because area of square = side*side]
Perimeter = 4*Side = 4*4.4 = 17.6 cm

As given that f(4)=13 then f(5)=13-5=8 --> substitute the value of f(5) back into the first equation: f(6)=f(5)-6=8-6=2.

20 buses are running between two places P and Q. In how many ways can a person go from P to Q and return by a different bus? | [
"342",
"None of these",
"324",
"380"
] | D | Explanation :
He can go in any bus out of the 20 buses.
Hence He can go in 20 ways.
Since he can not come back in the same bus that he used for travelling,
He can return in 19 ways.
Total number of ways = 20 x 19 = 380. Answer : Option B | AquaRat_train |
