If `2%` of x is 20, then x=

Physical quantity x and y are related as y=4tanx .If at x=(pi)/(4) radian error in measurement of x is 2% then find % error in measurement of y at x=(pi)/(4)

Find % error in x, where x = (a^2 b^(3/2) )/ (c^(1/2) d^3) and % error in a,b,c,d were 1%,2%,4%,2% resp..

Find % error in x, where x = (a^2 b^(3/2) )/ (c^(1/2) d^3) and % error in a,b,c,d were 1%,2%,4%,2% resp.

15% of 524-2% of 985 + ? = 20% of 423

(x% of y+y% of x)=?a.x% of y b.y% of x .2% of xy d.xy% of 3

if x=a+bt+ct^2 where x is in metre and t in second. if error in the measurement of time is 2% . what will be the error in x?

An experiment measures quantities a , b , c and x the value of x is calculated from x=ab//c^(3) . If the maximum percentage error in a , b and c are 1% , 1% and 2% respectively, then

A 5 % fall in the price of X leads to a 10% rise in demand for X.A 2% rise in the price of Y leads to a 6 % fall in dmeand for Y. calculate elasticity of demand of X and Y.
