R = Radius of Orbit of earth = 1.5 x 10⁸ km = 1.5 x 10¹¹m

T = time Period of earth around the sun = 365 Days

After 27 days, food left = 4 × 200 = 800 soldier days worth of food. Since, now there are only 80
soldiers, this food would last for 800/80 = 10 days. Number of extra days for which the food lasts
= 10 – 4 = 6 days.

26 + (34 * 43) – 96 + 69 = 1461

So Option B is correct

54679 + 5982 + 32614 = 93275
312 * 69 = 21528
93275 – 21528 = 71747

So Option B is correct

original number – 10x + y
(10x + y) – (10y + x) = 27
9(x – y) = 27
x – y = 3
All the given options not follow the condition.

LCM*HCF = a*b
840*84 = 168*b, b = 420

Answer – b) 35% Explanation : weight of A is x and weight of B is 2x given that 60 kg weight is the 30% percent increase of the original weight, so (130/100)*W = 60, W = 600/13 kg (W = original weight) X + 2x = 600/13, x = 200/13 So weight of A = 200/13 and of B = 400/13 (120/100)*(200/13) + [(100 + a)/100]*(400/13) = 60 Solve for a. We will get a = 35%

Butanone:

It contains a ketonic group. Ketones have suffix - one. Butane + one = Butanone

Let (a + b) = 6k, (b + c) = 7k and (c + a) = 8k.
Then, 2 (a + b + c) = 21k
2 × 14 = 21k
k = 28/21 = 4/3
(a + b) = (6 × 4/3) = 8
c = (a + b + c) - (a + b) = (14 - 8) = 6

Number of notes of Rs. 20 = 12
Number of notes of Rs. 10 = 12/4 = 3
Number of notes of Re. 1 = 7 × 3 = 21
Total amount = 12 × 20 + 3 × 10 + 1 × 21 = 240 + 30 + 21 = Rs. 291

Diameter of the hemispherical cup = 14 m
Therefore, radius of the hemispherical cup = 7 m
We know that,
Volume of the hemisphere 
Volume of sphere 
Let r be the radius of a stone.
According to the question,
350 × volume of stone = volume of hemispherical cup

700r³ = (7)³
r³ = 0.49

Therefore, radius is 0.79 m.

The correct answer would be Option B.
