Question 1043680
He starts with {{{ x }}} amount of money
Ashok spends 1/8 of the money for mangoes
That leaves him with {{{ x - (1/8)*x = (7/8)*x }}}
------------------------------
and 1/7 of the remaining money for sweets
That leaves him with:
{{{ (7/8)*x - (1/7)*(7/8)*x  = (6/8)*x }}}
{{{ (6/8)*x = (3/4)*x }}}
-----------------------------
He spends 1/6 of the money to buy bread for his father
That leaves him with:
{{{ (3/4)*x - (1/6)*(3/4)*x = (6/8)*x - (1/8)*x }}}
{{{ (6/8)*x - (1/8)*x = (5/8)*x }}}
----------------------------
He spends 1/5 and buys flowers for his sister
That leaves him with:
{{{ (5/8)*x - (1/5)*(5/8)*x = (4/8)*x }}}
{{{ (4/8)*x = (1/2)*x }}}
---------------------
He buys a cricket ball by spending 1/4 of the amount.
That leaves him with:
{{{ (4/8)*x - (1/4)*(2/4)*x = (4/8)*x - (1/8)*x }}}
{{{ (4/8)*x - (1/8)*x = (3/8)*x }}}
----------------------------
{{{ (3/8)*x = 48 }}}
{{{ 3x = 384 }}}
{{{ x = 128 }}}
Ashok had 128 at the beginning
----------------------------
check answer:
Ashok spends 1/8 of the money for mangoes
That leaves him with {{{ (7/8)*128 = 112 }}}
-------------------------------------
and 1/7 of the remaining money for sweets
That leaves him with: {{{ (6/7)*112 = 96 }}}
-------------------------------------
He spends 1/6 of the money to buy bread for his father
That leaves him with: {{{ (5/6)*96 = 80 }}}
-----------------------------------
He spends 1/5 and buys flowers for his sister
That leaves him with: {{{ (4/5)*80 = 64 }}}
-----------------------------------
He buys a cricket ball by spending 1/4 of the amount.
That leaves him with: {{{ (3/4)*64 = 48 }}}
He is left with 48
OK
