93

Explanation:

Predecessor means the before number and 94 before number is 93

Answer:

The man buys 11 lemons for 10.

So, cost price of one lemon is 10/11 =0.9rupees.

The man sells 10 lemons for 11.

So, selling price of one lemon is 11/10=1.1rupess.

So gain percent will be a ratio of substration of selling price to cost price with cost price.

\begin{gathered} \frac{(1.1 - 0.9)}{0.9} \times 100 \\ = 22.22\%\end{gathered}

0.9

(1.1−0.9)

×100

=22.22%

Answer:

Let the length of the rectangle be x units and the breadth be y units.

Area of the rectangle=length×breadth

=x×y=xy sq. units

From the given information, we have,

(x+2)×(y−2)=xy−28

and(x−1)×(y+2)=xy+33

(x+2)×(y−2)=xy−28

=>xy−2x+2y−4=xy−28

=>−2x+2y=−24

=>−x+y=−12

=>x=y+12....(i)

Also,(x−1)×(y+2)=xy+33

=>xy+2x−y−2=xy+33

=>2x−y=35....(ii)

Substituting equation (i) in equation (ii), we get,

2x−y=35

=>2(y+12)−y=35

=>2y+24−y=35

=>y=11

Substituting y=11 in equation (i), we get,

x=y+12

=>x=11+12

=>x=23

Therefore, length of rectangle =x=23 units

and breadth of rectangle =y=11 units

Area of rectangle =xy=23×11=253 square units
