Answer 1

Answer:

1.Assuming the number of One Rupee Coin is... …x,, and Two Rupee Coin is …y,. we get the following equation.

Given that The Number of Two Rupee Coin is 1/3 of One Rupee coin, then... x/3 = y, and total rupees is 115, And therefore...

x + 2.1/3 x = 115 ,

(2x + 3x)/3 = 115 or

5x = 345,

x = 69, and

y = 69/3 = 23.

23 coins of 2 rupee. Answer

2. Correct option is

C

143

Let breadth of the rectangle be 'b' cm.

So length of the rectangle will be 'b+2' cm.

Now

Perimeter =48

2(l+b)=48

2(b+2+b)=48

2b+2=24

2b=22

b=11 cm

l=b+2=13 cm

Then,

Area of the rectangle =lb

                                     =13×11

                                     =143 cm2
