If the percentage of A and G is 30% the percentage of T and C is

In a class, 15% of total number of students failed in Science, 25% of total number of students failed in Maths and 10% of total number of students failed in both. How much percentage of students passed in both Maths and Science?

the frequency changes by 10 % as the source approaches a stationary observer with constant speed v_(s) . What would be the percentage change in frequency as the sources reaccedes the observer with the same speed ? Given , that v_(s)lt lt v (v= speed pf sound in air )

The time period 'T' of a simple pendulum of length 'l' is given by T = 2pisqrt(l/g) .Find the percentage error in the value of 'T' if the percentage error in the value of 'l' is 2%.

A cuboid has volume V=lxx2lxx3l , where l is the length of one side. If the relative percentage error in the measurment of l is 1%, then the relative percentage error in measurement of V is

The percentage of marks obtained by a student in the monthly unit tests are given below: U n i t t e s t : I I I I I I I V V P e r c e n t ag e of m a r k s ob t a i n e d : 58 74 76 62 85 Find the probability that the student gets: a first class i.e. at least 60% marks marks between 70% and 80% a distinction i.e. 75% or above less than 65% marks.

The percentage error in measuring M, L and T are 1%, 1.5 % and 3 % respectively. Then the percentage error in measuring the physical quantity with dimensions ML^(-1)T^(-1) is :

The percentage error in the measurement of the voltage V is 3% and in the measurement of the current is 2%. The percentage error in the measurement of the resistance is
