The Pie chart given below shows the percentage-wise break up of students studying various specializations A.B.C.D.E and F in M.B.A. course in a university. The total numberof students howtook admission in MBA in that university is 8000. Study the chart carefully and answer the questions given below.
The ratio of the students studying C as specialization to students studying F as specialization is.
If x : y represent the ratio of the numberofstudents studying F and C to the numberof students studying D, then x - y =
Study the following data and answer the questions.
"In a study of 1500 rivers the following data were reported: 520 rivers were polluted by sulphur compounds, 335 were polluted by phosphates, 425 were polluted by crude oil, 100 were polluted by both crude oil and sulphur compounds; 180 were polluted by both sulphur compounds and phosphates; 150 were polluted by both phosphates and crude oil and 28 were polluted by sulphur compounds, phosphates and crude oil."
In a certain code, the $$r^{th}$$ letter of the English alphabet is coded as $$r + 10(\equiv mod 26)^{th}$$ letter cyclically. For example, $$4^{th}$$ letter D is coded as $$14^{th}$$ letter N and $$24^{th}$$ letter X is coded as $$8^{th}$$ letter H (because $$r + 10(\equiv mod 26)$$). The reverse process is used for decoding. Basing on this coding and decoding, answer questions.
