The total expenditure of a family, on different activities in a month, is shown in the piechart. the extra money spent on education as compared to transport (in percent) is ____.



Let total monhly earining = Rs. 100
Monthly spent on education = (15/100) x 100 = Rs. 15
Monthly spent on transport = (10/100) x 10 = Rs. 10
% money extra spent on education as compard to transportation
= ((15-10)/10) x 100 = 50%

The sum of two positive numebrs is 100. After subtracting 5 from each number, the product of the resulting numbers is 0. One of the original numbers is ______.


If the product of two positive numbers should be zero, one of the number must be zero.
After subtracting 5 if a positive number should become zero, that number should be 5.
If one number is 5 and the sum is 100 then the other number must be 95.
Let the two positive numbers be x and y.
∴ x + y = 100 ...(i)
(x – 5) (y – 5) = 0 ...(ii)
⇒ x = 5 or y = 5
If x = 5 then y = 95
If y = 5 then x = 95
∴ One of the number is 95 since 5 is not in any of the options.

Insert seven numbers between 2 and 34, such that the resulting sequence including 2 and 34 is an arithmetic progression. The sum of these inserted seven numbers is ________.


2, a , (a + d ), (a + 2d ), ...... (a + 6d ), 34
∴ Total number of terms of AP (n) = 9
Let sum of seven inserted numbers = S
∴ S = (7/2)[a+(a+6d0] = 7[a + 3d]
Tn = 34
Also, a – 2 = (a + d – a)
⇒ a – d = 2
Similarly a – 2 = 34 – (a + 6d)
⇒ a – 2 = 34 – a – 6d
⇒ 2a = 36 – 6d = 36 – 6(a – 2)
⇒ 2a = 36 – 6a + 12
⇒ 8a = 48
⇒ a = 6
∴ d = a – 2 = 6 – 2 = 4
∴ S = 7(a + 3d ) = 7(6 + 3 × 4) = 126

The data for an agricultural field for a specific month are given below:
Pan Evaporation = 100 mm
Effective Rainfall = 20 mm (after deducting losses due to runoff and deep percolation)
Crop Coefficient = 0.4
Irrigation Efficiency = 0.5
The amount of irrigation water (in mm) to be applied to the field in that month, is


Water required by crop = 100 × 0.4 mm = 40 mm
Effective rainfall = 20 mm

Uniform flow with velocity U makes an angle θ with the y-axis, as shown in the figure

The velocity potential (φ), is


Velocity in x-depth, ux = u sin θ
Velocity in y -depth, uy = u cos θ

Integrating it φ =–uxx + f (y ) + c
= –(u sin θ) x + f (y) + c ...(i)

Integrating it φ =–uy y + f (x) + c
= –(u cos θ) y + f (x) + c ...(ii)
By equation (i) and (ii),
φ = −u ( x sinθ +y cos θ)
If we take 
Then φ = u ( x sin θ + y cos θ)
So, φ = ± u ( x sinθ + y cos θ)


An amount of 35.67 mg HCl is added to distilled water and the total solution volume is made to one litre. The atomic weights of H and Cl are 1 and 35.5, respectively.
Neglecting the dissociation of water, the pH of the solution, is


HCl → H+ + Cl
1 mole of HCL gives 1 mole H+ ions
36.5 gm of HCl gives 1 gm of H+ ions
35.67 mg = (1/36.5) x 35.67 = 0.977 mg of H+

pH = –log10[H+] = –log10[9.77 × 10–4]
= –log109.77 + 4 log1010
= 4 – 0.989 = 3.01
