12 labours construct 120 toys in 8 days working 8 hours per day. If two of them leave the work, then how many days are required to do the same work with a working of 6 hours per day.
32 (5 is the sum of digit)
32+5 = 37 (10 is the sum of digit)
37+10 = 47 (11 is the sum of digit)
47+11 = 58 (13 is the sum of digit)
58+13 = 71 (8 is the sum of digit)
71+8 = 79

In a hospital there is a consumption of 1350 litres of milk for 70 patients for 30 days. How many patients will consume 1710 litres of milk in 28 days.
A and B entered into partnership with capitals in the ratio 4 and 5. After 3 months, A withdrew 1/4 of his capital and B withdrew 1/5 of his capital. The gain at the end of 10 months was Rs.760. The share of A in this profit is:
Let their initial capitals be 4x and 5x.
After 3 months A withdrew (1/4)*4x = x and B withdrew (1/5)*5x = x.
Therefore Ratio of capitals = (4x*3 + 3x*7 : 5x*3 + 4x*7)
= 33x : 43x = 33:43
A's share = Rs.(760 * 33/76) = Rs. 330
Let the annual payment be Rs. x
Then
(Amt of x for 4 years) + (Amt of x for 3 years) + (Amt of x for 2 years) + (Amt of x for 1 year) + x = 580
[x+ (x*4*8)/100] + [x+ (x*3*8)/100] + [x+ (x*2*8)/100] + [x+ (x*1*8)/100] + x = 580
