1.	The mean of four numbers a, b, c, d is 100. if c = 70, then the mean of the remaining numbers is
Answer» $\textsf{Given:}$ $\textsf{Mean of a,b,c and d is 100}$ $\mathsf{Mean=\displaystyle\frac{\Sigma{x}}{n}}$ $\implies\mathsf{100=\displaystyle\frac{a+b+c+d}{4}}$ $\implies\mathsf{100{\times}4=a+b+70+d}$ $\implies\mathsf{a+b+d=330}$ $\textsf{The mean of the remaining 3 numbers=}\mathsf{\displaystyle\frac{a+b+d}{3}}$ $\textsf{The mean of the remaining 3 numbers=}\mathsf{\displaystyle\frac{330}{3}}$ $\therefore\textsf{The mean of the remaining 3 numbers=110}$ Find more: If the mean of 17, 19, 24, 15, 18, 16, x, 14 is 17.
