What should come in place of the question mark (?) in the following question?
36(½) x 64(⅓) ÷ 8(⅓) = ?
An equilateral triangle circumscribes all the six circles, each with radius 1 cm. What is the perimeter of the equilateral triangle?
DE = GH = 4, ∠ADG = 60°
Then from 30 - 60 - 90 theorem
AG = 3√, BH =3√, then
AB = AG+GH+BH
Then perimeter of △ABC = 3×(3√+4+3√)=3×(23√+4)=6(3√+2)
Divide 800 into two parts such that the ratio of one may be to the other in the ratio 5:3?
8x = 800
x = 100
100 × 5 = 500

= 500, 300
A horse takes 2(½) seconds to complete a round around a circular field. If the speed of the horse was 66 m/s, then the radius of the field is :[Given π=22/7]
= Circumference of circle
= 2πr
Speed = 66 m/s
Time = 5/2
S=D/T
D=S×T
=66×(5/2)
D=165m
2π=165
=2×(22/7)×t=165
R = (165x7)/44 = 26.25m
In a mixture of 60 litres, the ratio of milk and water is 2 : 1. What amount of water must be added to make the ratio of milk and water as 1 : 2?
In the new mixture, the ratio of milk to water is 1 : 2.
if milk is 40 litres, water should be 80 litres;

Heena and Meena start walking from a fixed point in the opposite direction at an average speed of 2 Kmph. And 4 Kmph. Respectively. How many Km. will they be apart from each other in 5 hours?
Distance Covered by Meena = 4 x 5 = 20 Km
Total distance = (10 + 20) = 30Km
A man can row 15 kmph in still water and he finds that it takes him twice as much time to row up than as to row down the same distance in the river. The speed of the current is :
∴ Down stream speed = 15 + x kmph
Up stream speed = 15 - x kmph
Let the distance be d km.
∴ Down stream time = d/(15+x)
Upstream time = d/(15-x)
According to question,
2d/(15+x) = d/(15-x)
⇒ 2(15 - x) = (15 + x)
⇒ 30 - 2x = 15 + x
⇒ 15 = 3x
⇒ x = 15/3 = 5
∴ speed of current = 5 kmph
For what value of m, the system of equations mx + 2y =2 and 3x + y = 1 will be coincident?
I.e. a1/a2 = b1/b2 = c1/c2
for a1 x +b1 y = c1
and a2x +b2y = c2
∴ m/3 = 2/1 = 2/1
⇒ m = 6
If the numerator of a fraction is increased by 200% and the denominator is increased by 350%, the resultant fraction is 5/12 . What was the original fraction?
if x+y = 25 and x2y3 +y2x3 =25, what is the value of xy?
x2y3 +y2x3 =25
⇒ x2 y2 (x + y) = 25
⇒ (xy)2 (x + y) = 25
⇒ (xy)2 = 1
(∵ x + y = 25)
⇒ xy = ± 1

7x = 14000
x = 2000
Find the measures of an angle which is the complement of itself.
measure of its complement = x°
∴ x°+x°= 90° ⇒ x° = 45°
Let a = sin2A, b = cos2A, so that

(101)4/(100)4 = (101/100) 2t
(101/100)4 = (101/100) 2t
2t = 4
t = 2 years
