The least possible Venn-diagram is-

Conclusions:

I. Some Yahoo are Zoho.(It does not follow as its just possibility, not surety.)

II. All Yahoo can be Zoho.(It never will follow as No Zoho is a Gmail and Some Gmail are Yahoo.)

III. No Gmail is a Yahoo.(It does not follow as its obvious from the above diagram.)

Hence, option C is the correct answer.

Let the present age of sisters be 3x and 4x years.

Then, 5 years ago –

⇒ 9x - 15 = 4x - 5

⇒ 5x = 10

⇒ x = 2

Present age of elder sister = 4 × 2 = 8 years

Present age of younger sister = 3 × 2 = 6 years.

Required ratio of age after 5 years = 6 + 5 : 8 + 5 = 11 : 13

Option B is correct.

(9 + 3 − 16 ÷ 4 + 10) + {(3 + 5 × 2 ÷ 10)} × (18 – 4 of 5)

(22 − 4) + (3 + 1) × (18−20)

18 + 4 × (−2) = 18 − 8 = 10

Hence, option D is the correct answer.

Kepler’s second law states that a line between the sun and the planet sweeps equal areas in equal times.

• This law infers that the speed of the planet increases as it nears the sun and decreases as it recedes from the sun.

• First law of kepler states that the orbit of every planet is an ellipse with the Sun at one of the two foci.

• Johannes kepler published these laws between 1609 to 1619.
