A jar contains 24 Lt of sugar solution with sugar concentration of 12.5%. What percent of water should be added to reduce the concentration to 10% a. 25 b. 20 c. 28.56 d. None of these I'm getting 6lt of water to be added in this. But how to find percentage?? What to take in the base? 21?? 30?? Or 24??
A mixture of acid and water contain 30% acid. If it is kept open, 40% of the water evaporates every hour. Additionally, to increase the concentration, the solution can be boiled. If concentration of acid is required to be 60% at the end of one hour, then how much water should be evaporated by boiling from a solution of 25L

2x + 3y + 5 = 0 and 6x – 4y + 9 = 0 are two lines. If a point is at a distance of 1 unit from each of the two given lines, then how many such points exist?
Anyone from Chennai? Please respond. I Have a query
ABC is a right angled isosceles triangle with angle B being 90°. If D is a point on AB so that ∠DCB = 15° and if AD = 35 cm, then find length CD.
In triangle ABC, AB = 6 and AC = 9. AD is the internal angle bisector of angle A and D lies on BC such that BD = 2 and CD = 3. Find the length AD.
Please evaluate my profile. X- 7.8 /10 XII - 78.6% B.tech - 7.19/10 15 months experience as an IT consultant in an IT firm. I'm scoring north of 97 percentile in mocks, is it realistic for me to apply and target for SPJIMR or not ?
In trapezium ABCD with AB and CD being the parallel lines, EF is a line parallel to the parallel sides and it divides the trapezium into two equal areas. If AB = 8 and CD = 12, find the length of EF. (1) 10 (2) 96 (3) 104 (4) 9.6

Square ABCD, with side = 3 cm, is rotated by 45 degree keeping its center fixed to result into another square PQRS. What is the area of the region common to the two squares?
Could anybody please explain in detail?
The weight of a bucket increases by 33.33% when
filled with water to 50% of its capacity. Which of
these may be 50% of the weight of the bucket when
it is filled with water (assume the weight of bucket
and its capacity in kg to be integers)?
A watch gains by 2% per hour when the temperature
is in the range of 40°C–50°C and it loses at the
same rate when the temperature is in the range of
20°C–30°C. However, the watch owner is fortunate
since it runs on time in all other temperature ranges.
On a sunny day, the temperature started soaring up
from 8 a.m. in the morning at the uniform rate of
2°C per hour and sometime during the afternoon it
started coming down at the same rate. Find what
time will it be by the watch at 7 pm, if at 8 am the
temperature was 32°C and at 4 pm, it was 40°C.
Can we solve this question using equations only? I solved it using equations. Is their any easier method?
Answer is 7
method plese
Answer is 30 but I want to know the method. Took around 3 minutes in the mock.
