To find the angle between hour hand and minute hand, when minute hand is ahead of the hour hand. We use formula

The formula is,

= 30((M/5) – H) – (M/2)

= 30((45/5) – 7) – (45/2)

= 30( 9 – 7) – (45/2)

= 60 – (45/2)

= (120 – 45)/2

= 75 / 2

= 37(1/2) Degree

Hence, the angle between the minute hand and hour hand at time 45 minutes past 7’O clock is 37(1/2) Degree

Discount% = (MP - SP)/MP × 100

SP = MP - (Discount%/100) × MP

Let the cost price be Rs. X

Marked price = X + (45/100) × X = 1.45X

Discount = 20%

SP = 1.45X - (20/100) × 1.45X = 1.16X

Profit% = (SP - CP)/CP × 100

Profit% = (1.16X - X)/X × 100 = 16%

Avergae of 10 numbers = 30

⇒ (Sum of 10 numbers)/10 = 30

Let cost price of First article be Rs. X

Profit % = 40%

So, Selling price = x + 40% of x = x + 0.4x = 1.4x = 7x/5

And, Selling price of second article = Rs. x

Loss % = 40%

Cost price = Selling price + loss % of cost price

⇒ (1 - loss%) cost price = selling price

⇒ (1 - 0.4)Cost price = x

⇒ 0.6 cost price = x

⇒ Cost price = x/0.6 = 5x/3

∴ Required ratio = (7x/5) ∶ (5x/3) = 21 ∶ 25

Ajay can complete the work in 20 days and Vijay can complete the same work in 16 days, with the assistance of Suraj, they complete the work in 8 days,

1) Rectangle represents Bread.

2) Circle represents Pizza.

3) Triangle represents Burger.

4) Square represent Cheese.

Letter which represents cheese and bread i.e. letter which represents square and rectangle which is letter “B”.

Hence mark “none of the above” as your answer.

In right angle triangle;

One of the angles = 90° 

Let other two angles, (Aand B) 

Therefore, sum of all the angles = 180° 

=> A+B + 90° = 180° 

=>  A+B= 90° --(1) 

From the question;

A - B = 20 -- (2) 

By solving (1) & (2) we get;

A+B = 90

A- B  = 20

--------------

2B = 70 

=> B = 35°

=> A  = 55°

=> C = 90°

We count the squares in increasing order of size:


Hence, there are 40 squares in the given figure.

Hence, figure given in option 4 will complete the pattern.

∵ (a + b)³ = (a³ + b³) + 3ab(a + b)

⇒ (40)³ = 16480 + 3ab(40)

⇒ 64000 = 16480 + 120ab

⇒ 120ab = 64000 – 16480

⇒ ab = 47520/120

∴ ab = 396

Draw X and Y’s position in straight line,

Now they interchange their position and X becomes 7th from left end.

Now we can see X is 7th from left end and 14th from right end.

So, total boys in this row = 7 + 14 – 1 = 20.

Option ( c)  75  is correct. 

:- Let total distance travelled =2x

We know, time = distance/speed

Therfore, T1= x/15 

                T2 = x/5

=>  T1+T2 = 10 hours 

=> x/15 + x/ 5 = 10

By solving the equation, 

x  = 37.5

Therefore, Total distance traveled =  2x

                                    = 2*37.5 = 75 km.
