(a) 2900

(b) 3500

(c) 4000

(d) 5600

Solution

S1.Ans.(c); Number which are divisible by 2, 3 and 7 should be multiple of 2, 3 and 7 i.e. 42

So,

Required number=700/42–300/42

=16 – 7 (taking integral values) = 9

S2.Ans.(c); Share of C=2/5×5000 =2000

S3.Ans.(a); Total material in cylinder

=22/7×9×9×9 =(22×729)/7 =16038/7

Total material in cone

=1/3×22/7×9×9×36 =21384/7

Percentage of material wasted =(5346/7)/(21384/7)×100 =25%

S4. Ans.(a); Selling price=80/100×3840 =Rs.3072

S5. Ans.(c); Let C.P. of mixture = Rs. x /kg

So,120/100×x=324

x=324/6×5 =270

By using alligation

m/n=10/30 =1∶3

S6.Ans.(d); Sum of age of Ram and Rahim = 18 × 2 = 36 years

Sum of age of Rahim and Ramesh = 25 × 2 = 50 years

Sum of age of Ram and Ramesh = 29 × 2 = 58 years

Sum of ages of all=(36+50+58)/2=72

Age of eldest of three = 72 – 36 = 36 years

S7.Ans.(d); Let CP = x

x + profit = 540

x – Loss = 370

so, 2x = 910

x = 455

percentage profit=(910 –455)/455×100

=455/455×100 =100%

S8.Ans.(c); 65% pass in History

55% pass in Hindi

35% failed in History

45% failed in Hindi

30% failed only in History

40% failed only in Hindi

Total failed = 30% + 40% + 5% = 75%

Total passed = 25%

S9.Ans.(b); Total distance=3/4×16.5 km =12.375 km

Distance covered in one revolution = 2πr

=2×22/7×21/2= 66 cm

Number of revolution=(12.375×1000×100)/66 =18750

S10.Ans.(c); Let amount invested in each scheme be X, Y and Z

3% x = 5% y = 8% z = K

x∶ y∶ z=K/3 ∶K/5 ∶K/8 =40∶24∶15

Money invested at 3%=40/79×7900 =Rs.4000
