Problems based on Numbers Test 1

Let four consecutive prime numbers be x, y, z and P.
Product of x, y, z = 385.
Product of y, z, p = 1,001.
Now $\frac{\mathit{y}\mathit{z}\mathit{p}}{\mathit{x}\mathit{y}\mathit{z}}=\frac{1001}{385}$
$\frac{\mathit{P}}{\mathit{x}}=\frac{26}{10}$
$\frac{\mathit{P}}{\mathit{x}}=\frac{13}{5}$
$\mathit{P}=13,\mathit{x}=5$
So, the prime numbers = 5, 7, 11, 13.
The largest prime number = 13.
