Answer
# 1
VLSM Stands for Variable Length Subnet mask.This method is 
an advanced version of IP Subnet Zero Method of Subnetting.
It  is used to reduce the wastege of IP address over a WAN

# 2
VLSM is used for proper implimentation of IP addresses 
without any loss.In real world this is used by the ISP to 
Distribute the public Ip when asssigning the WAN links.
Basically companys who requires WAN link we need to use 2 
IP addresses ,One at our terminal and another in ISP 
terminal.But a single Class C address provides 254 valid 
host addressses what to do with rest 252 addresses.Throgh 
VlSM we can use it in 2 Valid host per subnet.Rest of all 
addresses can also be distributed with a Separate block 
size or 6,14,30,62 hst per subnet.

Answer
# 3
Allows for the creation of efficient, scalable addressing
schemes.
One of the modifications that has helped to bridge the gap
between IPv4 and IPv6 (128bit)
RIP V1 for small networks – RIP V2 scalable by using VLSM
With VLSM, a network administrator can use a long mask on
networks with few hosts, 
and a short mask on subnets with many hosts
