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

When the numbers are in AP, it means the difference between any two numbers is same,

The product of the two smallest parts is 483,

From the options, only in option 4, the product of the two smallest number is 483, 21 × 23 = 483

∴ The numbers are (21, 23, 25)

The student's union formation shall be a step towards giving to students the basic education in the field of politics. However, it shall create the same political atmosphere in the campus. Thus, both arguments hold strong.

The relation among the given numbers is:

3 × –2 = -6

3 × – 4 = –12

3 × 5 = 15

3 × – 6 = –18

Hence, “–12” is the missing term.

In the given statement, assumption I is not related to the bad condition of the road. Hence the assumption I is not implicit. The statement gives us no information regarding the availability of another route, hence assumption II is not implicit. 

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

⇒ Sum of 10 numbers = 300

⇒ 17 and 24 are mistaken as 71 and 42

⇒ New sum = 300 - 71 - 42 + 17 + 24 = 228

∴ New Average = 228/10 = 22.8

After 5 years Aman’s age = 23 years

So present age of Aman = 23 – 5 = 18 years

For same S.I, the ratio of amount invested is given by,

⇒ x/y = r₂t₂/r₁t₁ [where r₁t₁ is the rate and time at which Rs. x is invested and r₂t₂ is the rate and time at which Rs. y is invested]

⇒ x/y = (6.25 × 8) / (9 × 5) = 10 ∶ 9

As per given coding language,

Maple can be coded as ‘rin’

And according to options, ‘patricrin’ and ‘rindid’ have code ‘rin’ but ‘did’ is the code for ‘tree’.

Let, speed of stream = x km/hr

Speed of boat = 38 km/hr

∴ Upstream speed = (38 - x) km/hr

According to problem,

⇒ 2(38 - x) = 56

⇒ 38 - x = 28

⇒ x = 10

∴ Speed of the stream = 10 km/h

• Aqua regia is a mixture of Nitric acid and Hydrochloric acid in 1:3.

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
