ABCD is a rectangle. The points P, Q lie inside it with PQ parallel to AB. Points X, Y lie on AB (in the order A, X, Y, B) and W, Z on CD (in the order D, W, Z, C). The four parts AXPWD, XPQY, BYQZC, WPQZ have equal area. If BC = 19, PQ = 87, XY = YB + BC + CZ = WZ = WD + DA + AX, then the length of AB is

Rakesh travels from A to B at a speed of x kmph and then rests at B for x hours. Again he travels from B to C at a speed of 2x kmph and rests at C for 2x hours. He moves further to D at a speed twice as that between B and C and reaches D in 16 hours. If distances A to B, B to C, C to D are all equal to 12 km, the time for which he rested at B could be

The percentage content of an acid in three solutions forms a geometric progression. If we mix the first, the second and the third solutions in the ratio 3 : 2 : 1 by weight, we get a solution containing 22% acid. On the other hand, if we mix the solutions in the ratio 2 : 3 : 4 by weight, we obtain a solution containing 32% acid. Find the percentage of acid in each solution.
16%, 32%, 48%
27%, 9%, 3%
12%, 24%, 48%
32%, 18%, 12%
