SSC GD 2018 Question Paper Hindi (21-Feb2019) (Shift 1)

$A$ can complete $\frac{2}{3}$ of a work in $8$ days. $B$ can complete $\frac{3}{5}$ of the same work in $12$ days and $C$ can complete $\frac{4}{9}$ of the same work in $8$ days. If $A$ and $B$ worked together for $5$ days, then find how much time (in days) will $C$ alone take to complete the remaining work?

Let $x$ be the least multiple of $29$ which when divided by $20,21,22,24$ and $28$ leaves the remainders $13,14,15,17$ and $21$ respectively. What is the sum of digits of $x$?

$A$ takes $6$ hours more than $B$ to cover a distance of $60\text{ km}$. But if $A$ doubles his speed, he takes $3$ hours less than $B$ to cover the same distance. The speed (in $\text{km/hr}$) of $A$ is:

Two vessels $A$ and $B$ contain solutions of acid and water. In $A$ and $B$, the ratios of acid and water are $7:3$ and $4:1$, respectively. They are mixed in the ratio $1:2$. What is the ratio of acid and water in the resulting solution?

A $280\text{ m}$ long train is running at $108\text{ km/hr}$. In how much time will it cross a bridge of length $170\text{ m}$?
