Round 35.78 to 36 and 1005 to 1000 and 0.3012 to 0.3

Square root of 36 is 6 and cube root of 1000 is 10

So we will get

6 * 10
--------
0.3

=200

Can I ask one more? :/

Q- 21

Awesome12 Q:21 from the same paper.

(a) The tens digit cannot be less than 2 and there's no zero so it has to be greater than 20.
(b) First digit has to be 3 probability of choosing it is 2/6 and for second its 1/5 as only one is left and total remaining are 5. Multiply them and you get 1/15.
(c) For 43 first digit has to be 4 so its probability is 3/6 and for second digit 3 its 2/5 as number of 3's is same. For 32 its 2/6 for first 3 and 1/5 for the 2. Multiply them and you get 3/15 and 1/5 respectively. Add both and 4/15 is the final answer.

Kevin's speed = d /T

d = Kevin's speed * T


Jane's speed is 1o % faster than Kevin (ie. Jane's speed = Kevin's speed * (110/100) )

Jane's speed (i.e Jane's speed = Kevin's speed (d/T) * (110/100)) = d/t

d ......... 110 ....... d
--- * ------ = ----
T ........ 100........ t

Find t

Extend AC horizontally and that will give a value of 5 till A.Divide 5/k to and then turn it into minus to get the required cos of -5/k

 

[exploded diper]

at some places it says ( +- ) ans .. does that mean it is opptional to right + - with the answer or do we have to?
