Half of the cloth = 37.5/2
From 1 meter he will make 8 pieces
=> in 37.5/2 ---- ?
37.5/2 x 8
= 150.
Given a secret is told to 3 persons in 3 minutes.
And if the process continues with each person saying 3 other persons,
In 30 minutes => the rocess for 10 times because each person time is 3 minutes.
Required number of persons =
Now it forms a geometric progression,
Sum to n terms is
Here a = 3, r = 3
=> 59048 x 3 /2
= 88572.
Given,
5sinx + 12cosx ? -r
cosx) ? -r
= cosA => sinA =
=> 13(sinx cosA + sinA cosx) ? -r
=> 13(sin(x + A)) ? -r
we know that , -1 ? sin (angle) ? 1
=> 13sin (x + A) ? -13
Using BODMAS Rule,
First solve division, mutiplication and Addition
So here 10/2 = 5
Then 2 x 5 = 10
Now, 5 + 10 = 15.
Hence, 5 + 2 x 10/2 = 15.
=
50.003% of 99.8 ÷ 49.988 = ?
? ~= (50 x 100/100)/50
? ~= (50 x 100)/(100 x 50)
? ~= 1
=> - 4KL/4K = a/b
=> L = - a/b
=> bL = -a
64/12 = 16/3 in simplest form.
56/32 can be reduced as
56/32
= 28/16
= 14/8
= 7/4
= 1 3/4
= 1.75
Hence, simplified value of 56/32 = 3/4 = 1.75.
26 trees have 25 gaps between them,
Required distance (225/25) = 9
Given teacher drinks 9 ltr
Let number of boys be 'A'.
Let number of girls be 'B'.
Boy drinks 7 ltr and girl drinks 4 ltr
After class total water consumed = 42 ltr
Then,
9 + 7A + 4B = 42
=> 7A + 4B = 33
By trial and error method,
The only integers which satisfy the equation is A = 3 and B = 3
Therefore, number of girls in the class = 3.
