$\large\mathcal{\orange{\overbrace{\green{\underbrace{\orange{SOLU}\green{TION}}}}}}$

GIVEN :-

• Daniel spent $\rm{\dfrac{2}{5}}$ of his money on buying food for his family .

• Daniel spent $\rm{\dfrac{2}{7}}$ of his remaining money on buying books .

• Daniel initially had Rs. 3909.50 money .

TO FIND :-

• How much did he spend on buying books .

CALCULATION :-

✍️ Money spent on buying food for his family,

$\rm{=\:\dfrac{2}{5}\:of\:the\:total\:money\:}$

$\rm{=\:\dfrac{2}{5}\:\times{3909.50}\:\:=\:\:Rs.1563.80}$

$\checkmark\:\rm{\purple{\implies\:Money\:spent\:on\:buying\:food\:is\:\:Rs.1563.80\:}}$

✍️ Remaining money,

= (3909.50 - 1563.80)

=> Remaining money = Rs. 2345.70 .

✍️ Now, Money spent on buying his books,

$\rm{=\:\dfrac{2}{7}\:of\:his\:remaining\:money\:}$

$\rm{=\:\dfrac{2}{7}\:\times{2345.70}\:\:\:=\:\:Rs.670.20}$

$\bigstar\:\rm{\blue{\boxed{\implies\:Money\:spent\:on\:buying\:books\:is\:\:Rs.670.20\:}}}$
