As a toddler when I looked at my fingers and wondered, you helped me to count numbers. As a kid when I looked at stars with awe, you helped me and told that's infinity. As a teen when my confused mind often went blank, you told that's zero and eventually

Reply Like? Yes | No

(11 years ago)

1.1x = 396 => x=360
0.9y = 396 => y=440

So total price = 440+360 = 800
Selling Price = 792

Total Loss = 8 rs

Like? Yes (1) | No (1)

(11 years ago)

When profit and loss % are same, it is always a loss.
Loss % = (Common loss and gain %)^2 / 100
so, (10)^2/100 = 100/100 = 1% loss.

let the length of the candle be 100.
then first time 1/3 rd will burnt.so,
100/3=33.33 burnt.remaining=100-33.33=67.77
2nd time also 1/3 rd will burnt.so
67.77/3=22.66 burnt.remaining=67.77-22.66=45.11
similarly,
3rd time remaining = 30.074
4 th time = 20.05
5 th time = 13.37
6 th time = 9 (approx)
so in the total length 10 cm is 10 % value.

TCS Test pattern has changed for 2014 recruitment and following are the changes,

1. New Verbal Ability Section has been added, it will have 1 question for 10 minutes.

The question is to write an Essay / Business Letter of 70-100 words utilizing all different words / phrases of words given as part of question.

Sample: Using the following words write an email with minimum of 70 words to the Customer Mr John Nixon about the delay in the project

Payment Processing System - Schedule - 10th May (Friday) - will not recur - total delay - regret

How the Verbal ability section is assessed?

The test taker will be asked to frame a paragraph of 70-100 words using some words / phrases of words given as the question. The Online Test engine of Touch Stone will automatically assess the Essay/ business letter / Paragraph written by the test taker in-terms of Grammatical correctness and effective utilization of words.

The result is Yes / No, so based on the correctness of Essay in terms of Grammar and utilization of all given words/phrases, the test taker will either be selected or rejected in the Test.

2. Change in Analytical ability section:

There will be two kinds of questions with two respective weightage of marks, ones with * mark and others without * mark
Questions with * mark -> All questions with * carry higher marks than the questions that do not have * mark. And * marked questions are difficult questions.
There will be negative marking for all questions in Analytical Ability Section.

B is 5 more than A,D is 11 more than c,A is 23 more than D and total average is 22 then find the value of c?

Reply Like? Yes | No

(11 years ago)

Let C = x
D = x+11
A = x+11+23 = x+34
B = x+34+5 = x+39

so (x+x+11+x+34+x+39)/4 = 22
x = 22-21 = 1 = Value of C

(11 years ago)

the value of c is 1 here

Like? Yes | No (1)

(11 years ago)

b=a+5
d=c+11
a=d+23

as we have to fina the value of c we will write all the above equations in terms of c .

so
d=c+11
a=(d+11)+23=c+34
b=(c+34)+5=c+39

average of all is 22
so
a+b+c+d=22*4

now substituting values we get
c=1

Like? Yes (1) | No (1)

(11 years ago)

you can analyse from the question that c is the smallest no. in all four of them
so assume c as x

let c=x
d=x+11
a=d+23=x+11+23=x+34
b=a+5= x+34+5=x+39

avg=(a+b+c+d)/4=22
avg=(x+x+11+x+34+x+39)/4=22
4x+84=88
4x=4
x=1
therefore c=1
d=12
a=35
b=40

Like? Yes (2) | No (2)
