Question

After spending 69 % of her money, a lady has rs. 93 left. How many had she at first?

Answer 1

let y be the total amt
31/100×y =93
y=9300/31
y=300
ans 300

Answer 2

69% is spent
Remaining = 31%
Remaining amount = Rs.93

Given : 31% == Rs. 93
            1% == 93/31 = 3
            100% == 100*3 = 300 Rs.
Hence she first had 300 Rs
Hope this helps
