- A costs four times as mush as B . A is sold at a loss of 35% and B is sold at a profit of 60%. If theselling price of A is Rs.1620 more than the selling price of B, what is the cost price of A?
61506600616164806250Option D

SP of A = 0.65*400x = 260x

SP of B = 1.6*100x = 160x

Diiference = 260x – 160x = 1620

=> x = 16.2

CP of A = 400x = 400*16.2 = Rs.6480 - A solution of ‘Nimboopani’ has 35% sugar. Another solution has 15% sugar. How many litres of the second solution must be added to the 40 L of first solution to make a solution of 25% sugar?
6040805020Option B

Sugar in first solution = 40*35/100 = 14L

Sugar in second solution =15*x/100 = 3x/20L

Total quantity = 40+x L

Now , [14+3x/20]/(40+x) = ¼

=>x = 40 L - A and B enter into a partnership with their capital in the ratio of 16:9 resp. At the end of 6 months, B withdrew his capital. If they receive the profits in the ratio of 32:27 resp. For how many long is A ‘s capital used?
56324Option E

A withdew capital after x months .

(16*x)/(9*6) = 32/27

=>x = 4 - A man can row 15 km/hr. in still water and he finds that it takes him twice as much time to row upstream as to row downstream . Find the speed of water.
9511108Option B

[Dist./(15+x)]*2 = [Dist/(15-x)]

=>x = 5 km/hr. - 10 men and 15 children complete a certain piece of work in 25 days. If each child takes twice the time taken by a man to finish the work. In how many days will 35 children finish the same work.
1518202522Option D

1 M = 2C

Total work = (10M + 15C)*25 = 35C + 25

Time taken to complete the whole work = (35C + 25)/35C = 25 Days - ? =25% of 3632 + 16% of 3750 – 11^3
150152181165177Option E

? =25% of 3632 + 16% of 3750 – 11^3

=>? = 908 + 600 – 1331

=> ? = 177 - 10% of ? = 8^3 – 29^2 + 27^2 – 310 – 16*5
1009511588120Option A

10% of ? = 8^3 – 29^2 + 27^2 – 310 – 16*5

=>10% of ? =512 – 841 – 310 – 390

=>10% of ? = 10

=> ? = 100 - (1369)^1/2 * 10*4 + (2744)^3 *6*15 – (784)^1/2 *5 = ?
20002121250023202100Option D

(1369)^1/2 * 10*4 + (2744)^3 *6*15 – (784)^1/2 *5 = ?

=>? = 37*40 + 14*90 – 28*15

=>? = 1480 + 1260 -420

=>? = 2320 - 32% of 25% of 4600 = 10% of 40% of ?
81009000920085007500Option C

32% of 25% of 4600 = 10% of 40% of ?

=>10% of 40% of ? = 368

=>? = 9200 - 2304 / 16*(484)^1/2 – 13^3 = ?
859800900920971Option E

2304 / 16*(484)^1/2 – 13^3 = ?

=>144*22 – 2197 = ?

=>? = 971
