(a)
The number of pens remains unchanged.
Number of markers that Usha gave away or sold
= 4 u - 3 u
= 1 u
1 u = 29 + 50 = 79
Number of markers that Usha had at first
= 4 u
= 4 x 79
= 316
(b)
Total number of markers and pens that Usha had at first
= 1 u + 4 u
= 5 u
= 5 x 79
= 395
Answer(s): (a) 316; (b) 395
