Let the number of toys be 100

Difference = 63-59=4

4=100 toys

20=500 toys

Required toys==500×60/100=300

Q.2) b

Let as boys and girls be x and y,

((x×62)+(y×55))/(x+y)=58

62x+55y=58x+58y

4x=3y

x/y=3/4

Ratio = 3 : 4

Q.3) d

Score of Gopi=34×74+23×78-56×76=54

Q.4)

c

Sum of  11 numbers is=11×45=495

Average of new set number=(495+121)/11=56

Q.5) b

Let the number of runs scored in 10th inning be x,

9×40+x=10×43

360+x=430

x=70 runs

Q.6) c

Sum of salary  of X, Y and Z=3×12000=Rs.36000

Then money spend,

36000-(3×8000)=Rs.12000

3y+y+2y=12000

y=12000/6=2000

x=3y

x=3×2000=Rs.6000

Averange amount X and Y spend=(6000+2000)/2=Rs.4000

Q.7) d

Sum of price 39 product=39×150=Rs.5850

Sum of price of bags=15×250=Rs.3750

Simplify the above equation,

x=152

Sum of total cost=26×190=Rs.4940

(7×15+9×15+10×x)=4940

x=470

Q.11) (d)

Since the marked price of the article is not given, we cannot determine the required percentage.

Q.12) (b)

As the first person earns 20% more than the second person,

Required percentage = 20/(100+20)×100=16.67%

Q.13) (a)

The difference between the price= Rs.2.8 which is 4.35% of Rs.64.35.

Required percentage = 4.35/(100-4.35)×100=4.54%

Q.14) (a)

At the end of July, the count of cars=24000+50% of 24000=36000

At the end of august, the count of cars=36000+50% of 36000=54000

At the end of September, the count of cars=54000+50% of 54000=81000

Q.15) (c)

Given that,

95x/100+541.5=(2×95x)/100

X=Rs.570

Q.17) (e)

Cost price of a bat = 4500/12=375

Selling price of a bat = 3200/8=400

Profit percentage = (400-375)/375×100=20/3%

Q.18) (a)

Let us take the cost price of article be X.

For the first case,

88/100×85/100×95/100×x=0.7106x

For the second case,

90/100×90/100×88/100=0.7128x

Obviously, first offer is better.

Q.19) (c)

Let the cost price be x.

After successive discounts, the selling price be

94/100×90/100×86/100×2000=1455

He makes a profit of 1%,

So, 1455/101×100=1440

Q.20) (b)

Let the marked price be x.

If 10% discount is given, then the selling price would be  90/100×x=9x/10

Now, selling price = 9x/10

Gain =20%

CP = 100/120×9x/10=3x/4

Again, SP=85% of Rs. x = 17x/20

Gain = 17x/20-3x/4=x/10

Gain% =x/10×4/3x×100=40/3%=131/3%
