13, 24, 35, 46, 57, 68, 79... seven (7) two digit numbers are possible.
02+18 also gives 20 but 02 can not be considered as two digit number.

@karan..
368 units of water are added in 864 units of M.
864 units of M contain 120 units of A, 616 units of B and 128 units of C .
As concentration of B is 50% in final mixture, volume/wt of total mixture is 2*616=1232 units.
Hence 1232-864 = 368 units of water are added to 864 units of M. How you get 120 616, 128..

Product M ls produced by mixing chemical x and chemical Y in the ratio of 5 4. Chemical x is prepared by mixing two raw materials, A and B, in the ratio of 1 3. Chemical Y is prepared by mixing raw materials, B and C, in the ratio of 2 1. Then the final mixture is prepared by mixing 864 units of product M with water. If the concentration of the raw material B in the final mixture is 50%, how much water had been added to product M.

Hence 1232-864 = 368 units of water are added to 864 units of M.

864 units of M contains chemical X ( 480 units) and chemical y ( 384) as their ratio is 5:4 in M.
480 units of X contain 120 units of A and 360 units of B ( ratio 1:3).
384 units of Y contain 256 units of B and 128 units of C.
so 864 units of M contain 616 ( 360+256) units of B,
864 units of M contain 120 units of A, 616 units of B and 128 units of C.

Latest MBA Aptitude Question SOLUTION: ABCD is a trapezium with AB parallel to CD. AC is perpendicular to BC and BD is perpendicular to AD. If AD=BC=15cm and AB=25cm , find the area of the trapezium ABCD.

192 cm^2

BD= Sqrt ( 25^2-15^2) = 20
area of triangle ADB = 20*15/2= 150 sq cm
Height of triangle ADB= 2*150/25= 12 cms
Height for this triangle = equal to the height of trapezium.

so height of trapezium = 12cm.
By calculations, we get
CD=7cm

Area of trapezium =1/2*(AB+CD)*Height

Hence area of ABCD trapezium = (1/2)*(25+7)*12 = 192 sq. cm.

· 2. Average weight of a class of 60 students is 56 kg.
a. With the exit of two students, the average weight of the class reduces by I kg. What is the average weight of the students who leave the class?
b. If the weight of none of the students in the class of 60 was not less than 54 kg, what can be the maximum weight of any student in the class?

a. Let an average weight of two students who leave the class be x kg, then
Average weight of remaining 58 students=(60*56 - 2x)/58 = 55
=> 3360 - 2x = 3190 or x=85

b. To get the maximum weight of any of the student in the class, let us consider the remaining 59 students are of minimum weight of 54 kg, and 1 students of maximum weight is of 'x' kg, then
Total weight=59*54 + x = 60*56
=> x=3360 - 3186=174
