downstream in 12 minutes is

a)1.2 km b) 1.8 km c) 2.4 km d) 3.6 km

__ANSWERS:__

1.b) Tricks Take option choice

Ratio of amount by A, B, C = 7:6:3

Let Ans. is Rs.2000 so 30 % of 2000 is 6000

So, 70% of Rs.2000 is 14000

Only 14000 is divided by 16 (7+6+3) So this is answer

2.c) Tricks

56100 = {cost price *(110 * 120 * 85)}/ (100 *100* 100)

3.d) Tricks

Original price per kg = (20 *240)/ (80 *6)

4.d)

Distance covered = (40 + 60) =100 m Time taken 20 s

Required speed = (100/20) = 5 m/s = 18 km/hr

So, then Answer is 18 km/hr

5.b)

Installment = (debt *100) / [ (Time *100) + {1 +2+….(Time-1)*rate}]

= (6450 * 100) / [ 4*100 + {(1 + 2+3)*5}

= (6450 *100)/ (400+300 = 1500

So, answer is Rs 1500

6.a) If any amount is invested at 5 % for 2 years of C.I then interest he got

{5 + 5 + (5*5)/100} = 10.25 %

If any amount is invested at 5 % for 2 years at simple interest then interest he got = (5 + 5) = 10 % If 10.25 % of a sum = Rs. 328

Then 10 % of sum will be = Rs. (328 *10)/10.25 = Rs.320

7.d) Let selling price each of the article = Rs.100

Cost price of both article = 100 * 100 (1/175 + 1/70) =1400/7= 200

Total selling price = Rs. 200

So, no profit or no loss

8.d) Tricks

Speed of boat in still water =15 km/hr Rate of current =3 km/hr

Speed of boat travelling downstream = (15 + 3) km/hr = 18 km/hr

So, Distance travelled downstream in 12 minutes = 18 * (12/60) = 3.6 km
