Question

BOD values (in ppm ) for clean water (A) and polluted water (B) are expected respectively: (A) A > 50, B < 27 (B) A >25, B < 17 (C) A < 5, B > 17 (D) A > 15, B > 47

Tardigrade Admin · Accepted Answer

BOD values of clean water (A) is less than 5 ppm So A < 5 BOD values of polluted water (B) is greater than 17 ppm So B > 17

Q. BOD values (in $pp m$ ) for clean water $(A)$ and polluted water $(B)$ are expected respectively:

$A > 50, B < 27$

$A > 25, B < 17$

$A < 5, B > 17$

$A > 15, B > 47$

BOD values of clean water $(A)$ is less than $5 pp m$
So $A < 5$
BOD values of polluted water $(B)$ is greater than $17 pp m$
So $B > 17$

Q. BOD values (in ppm ) for clean water (A) and polluted water (B) are expected respectively:

A>50,B<27

A>25,B<17

A<5,B>17

A>15,B>47
